Chapter 1
Trapped in the Old Mindset
For nearly half a century, the four-minute mile was regarded as an unbreakable barrier. Doctors said it. Athletes said it. Scientists said it. The human body, the consensus ran, simply could not run a mile in under four minutes without something inside it giving way. It wasn’t merely difficult. It was believed to be biologically impossible.
Then, on the 6th of May 1954, on a damp, blustery afternoon at Iffley Road track in Oxford, Roger Bannister did the unthinkable. He ran a mile in 3 minutes and 59.4 seconds, and his name was etched into sporting history for as long as people care about such things.
But what happened next was, in its own way, more remarkable than the run itself.
Just forty-six days later, the barrier fell again. The Australian John Landy ran a mile in 3 minutes 57.9 seconds, taking the record Bannister had only just set. Within three years, a further fifteen runners had done the same. Within a decade, the four-minute mile had gone from impossible to ordinary. Today, it is considered a baseline for any elite middle-distance runner. Schoolboys have done it.
What changed?
Not the human body. Not training methods, not nutrition, not shoes — none of that had time to evolve in forty-six days. What changed was something far quieter and far more powerful.
What changed was belief.
The barrier was never in the body. It was in the mind.
This single example uncovers a deeper truth, one that runs like a seam through every life I have ever observed closely, including my own: the boundaries of our lives are rarely drawn by our circumstances. They are drawn by our thoughts. We are not, for the most part, trapped by prisons of steel or stone. We are trapped by inherited patterns of thinking, by limiting beliefs, by quietly internalised expectations passed down to us through families, cultures, classrooms and, perhaps most powerfully, past failures.
These are the mental shackles. And they decide what we will even attempt, let alone achieve.
Epictetus, the old Stoic, said it plainly: “It is impossible for a man to learn what he thinks he already knows.”If you believe your way of thinking is already complete, already correct, already finished, you are unlikely to grow. A closed mind lives in a small world. A fixed mindset, in time, creates a fixed life.
Scripture says it more sharply still: “As he thinketh in his heart, so is he” (Proverbs 23:7, KJV). Your thoughts shape your reality. Not your circumstances. Not your CV. Not your postcode. The thoughts that live not just in your head but in your heart — those are the ones that determine the direction, the depth and the destiny of your life.

Mind over matter
Modern psychology has caught up with this biblical truth, and in some ways is still trying to catch up further.
The concept of cognitive bias tells us that our brains are not the impartial observers we like to think they are. They actively seek out information that confirms what we already believe. If you have decided the world is against you, you will find evidence everywhere. If you have decided that nothing ever quite works out for you, your brain will helpfully highlight every inconvenience and quietly delete every breakthrough.
This is confirmation bias, and it makes growth extraordinarily difficult, because your brain is filtering the world through the framework you already have.
Sitting alongside it is something called cognitive dissonance — the deep mental discomfort you feel when you are confronted with a truth that contradicts your current beliefs. The instinct, almost always, is not to update the belief. It is to retreat into the familiar pattern, because the familiar pattern feels safe, even when it is the very thing harming you.
In other words, your brain will work hard to protect your current mindset, even if that mindset is the thing keeping you stuck.
But the Bible offers a different road. “Be transformed by the renewing of your mind” (Romans 12:2, NKJV). The Greek word for transformed is metamorphoō — the very same word used to describe Jesus’ transfiguration on the mountain, where his appearance was changed from the inside out. This is not surface adjustment. This is not a New Year’s resolution with better marketing. This is deep, radical transformation.
It is not self-help. It is a spiritual command.

What we focus on, we see
When I was younger, I became quietly obsessed with a particular car. I had seen it once in a magazine, and something about it caught me. I started reading about it — the different models, the engine sizes, the wheel options, the interior trims. And then a strange thing happened.
I started seeing the car everywhere.
On the motorway. In supermarket car parks. In adverts I had been scrolling past for months. I discovered that my neighbour drove one. So did a former boss. The car hadn’t suddenly multiplied. It had always been there. What had changed was me. My mind had opened to the possibility of it, and now I could see it.
Neuroscientists call this reticular activation. There is a small bundle of nerves at the base of the brain that decides, largely without your permission, what is worth your attention and what isn’t. Once you tell it something matters, it begins to filter in what it used to filter out. You see what you are tuned to.
What had once been invisible became visible.
And the principle works in both directions, which is the sobering part. If you have stopped believing something is possible for you — because of past failures, because of how you were raised, because of what a teacher once said in front of a class, because of a relationship that ended badly — then you will stop seeing the opportunities that are right in front of you. They may be all around you. They may be standing in the room. But if your mind is closed to them, they remain invisible.
That is the power, and the danger, of a fixed mindset.
Growing up, I did not aspire to much. I came from an environment in which higher education simply wasn’t part of the conversation. Nobody around me had formal qualifications, so I didn’t pursue any either. My vision for life was narrow: get by, make some money, go out at the weekend, look good, have fun, find a girlfriend. That was enough for me. I wasn’t lazy. I just couldn’t see beyond what I had known. The vocabulary of purpose, legacy, calling, impact — none of it existed in my mind. The vision was too small. The mindset, too limiting.
Part of where that narrow vision came from, I think, was simply the life I grew up in. I had very little. My mother, for all her efforts, struggled with alcohol, and much of my childhood was lived hand to mouth. When the world has only ever shown you scarcity, scarcity becomes the lens through which you expect the rest of your life to arrive.
I remember one spring afternoon as a teenager, walking down Regent Street in London. The sun was out, the shop windows glittered with things I could not dream of affording, and people moved past me well-dressed and certain of themselves, as if they all had somewhere important to be. I had no money in my pocket and no direction in my heart. And I remember thinking, quite plainly: Why is this my story? Why is this my life?
And then a simple thought arrived — one I have never forgotten.
You’ve got to take the rough with the smooth.
It was not profound. It was not original. But something in me shifted. For the first time, I began to accept the difficulties of my life as part of a journey rather than a verdict on my worth. It was, though I could not have named it then, the first small turning of the very thing this book is about — a mind beginning to change. Not long after, I became a Christian, and I found something more precious than any change in my circumstances: a new way of thinking. A renewed mind. A mind that could not only see the rough, but could begin to anticipate the smooth.

Who told you that?
It would help, before we go any further, to stop and ask a question I have asked of myself many times, and that I now want to ask of you.
Who told you that?
Who told you that you weren’t clever? Who told you that you were the difficult one in the family? Who told you that people from your background don’t end up in those rooms, those jobs, those marriages, those callings? Who told you that you were too much, or not enough, or too quiet, or too loud, or too sensitive, or too late? Whose voice has been doing the narrating of your life?
Because here is the thing. Most of the limits we carry around inside ourselves were not put there by us. They were put there by someone else, often a long time ago, often by people who had no idea of the weight their words would carry. A father who said you’d never amount to much. A teacher who told a thirteen-year-old that they weren’t university material. A mother who, in a moment of her own pain, said you were just like the parent who left. A friend who laughed at the dream when you finally said it out loud. A partner who said no one else would ever want you.
And then there is the deeper trap, the one that comes not from words but from wounds.
When people have hurt us, we don’t just carry the memory of what they did. We carry the conclusions we drew afterwards. People can’t be trusted. Love always leaves. If I let someone in, they will use it against me. If I show up fully, I will be rejected. These are not character traits. They are survival strategies that hardened, over time, into a worldview. They kept us safe once. Now they are keeping us small.
You have to understand: a thought that begins as protection can end as a prison.

And yet — it’s yours now
Now I have to say something that will sit awkwardly for some readers, and I want to say it gently, because I know the weight of it.
You did not choose your upbringing. You did not choose your family, your country, your school, the words spoken over you, the wounds inflicted on you, the absences you grew up around. None of that was your fault. Not one bit of it.
But at some point — and only you can know when that point arrives — you become responsible for what you do with it.
Your past is not your fault. Your future is your responsibility.
Your thinking, especially, is your responsibility. Nobody else can renew your mind for you. Your mother can’t do it for you. Your pastor can’t do it for you. The book you are holding cannot do it for you. At some point, the responsibility for the way you think becomes yours, and yours alone.
This is, I have come to believe, one of the most freeing realisations a human being can have. Because if your thinking is your responsibility, it is also within your reach. You are not a passenger in your own head. You are not the helpless inheritor of every thought your family handed you. You can think about your thinking. You can challenge it. You can replace it. You can renew it.
The Apostle Paul, who as we have seen knew a thing or two about transformation, put it this way: we take captive every thought to make it obedient to Christ (2 Corinthians 10:5). Notice the language. We don’t passively receive our thoughts. We take them captive. We sit them down. We interrogate them. We ask them where they came from and whether they have any business still being here. And then, with the help of God, we decide which thoughts get to stay and which thoughts have to go.
That is responsibility. And it is also freedom.
*
A prison of the mind
Many people live in prisons of their own making — mental cages where the bars are constructed from old beliefs. People like me don’t succeed. I’m not clever enough. I always mess things up. I’ll never have a healthy relationship. I’m too far gone. I left it too late.
These are not facts. They are inherited thoughts, rehearsed and reinforced over years, until they feel like facts. And if thoughts got us into that prison, then new thoughts — and new thoughts alone — can get us out.
I have met people who are extraordinarily bright. Articulate. Insightful. Capable of grasping ideas that would defeat most of us. And yet they remain stuck — in jobs that drain them, in relationships that wound them, in cycles of addiction or procrastination they cannot seem to break. It is not for lack of potential. It is because something inside them still whispers you can’t. And they have believed the whisper.
Now, let me be careful here. Success is not the goal for everyone in the same way. Some people choose a simple, quiet life by design — to focus on family, on ministry, on faithfulness in a small place — and that is a beautiful and noble thing. There is a world of difference, however, between contentment and complacency. The issue is not the person who wants less. The issue is the person who wants more, who feels called to more, who senses there is more — and yet does not believe more is possible for them.
That is a prison.
The same pattern shows up in our relationships, often with painful clarity. Have you ever noticed that some people keep ending up with the same kind of partner, just in a different body? One selfish boyfriend replaced by another. One controlling spouse swapped for one who seems different at first and ends up the same. This is not bad luck. It is rarely a coincidence. It is, almost always, the outworking of an internalised belief. This is what I deserve. This is all I can get. This is what love looks like. If you grew up around dysfunction, you will, without meaning to, find yourself reaching for what is familiar — even when familiar means harmful.
People don’t just repeat behaviours. They repeat belief systems.
And until the belief system changes, the pattern won’t.

The door was never locked
Let me paint you a picture.
Imagine someone leads you into a small room, sits you down, and says they’ll be back in a moment. The door closes behind them. You wait. Time passes. Eventually you realise they aren’t coming back, so you stand up and go to the door.
It won’t open.
You push it. Nothing. You shove your shoulder against it. Nothing. You start to panic. You bang. You shout. You cry. After a while, you sit on the floor with your back against the wall, and you accept what now feels obvious: you are trapped.
Except the door wasn’t locked.
You were pushing a door that opens by pulling. You had never used that style of handle before. Nobody had taught you. The mechanism was three inches from your hand for the entire time you were trapped, and you didn’t know how to operate it.
I think about this far more often than I should, because life is full of doors like that.
There is a classic moment in Navy SEAL training — the famous American special forces selection course, often called the hardest military training on earth — where candidates are put through something known as drown-proofing. Their hands are bound behind their backs. Their feet are tied together. They are then dropped into a deep pool and required to survive.
The natural human instinct, when you cannot use your arms or legs and you are sinking, is to thrash. To fight. To kick harder, to twist, to claw at the water. And every single recruit who does what feels natural — fails. Many of them, frankly, end up needing to be pulled out by instructors.
Here is the secret the instructors are trying to teach. To survive drown-proofing, you have to do the one thing every cell in your body is screaming at you not to do.
You have to sink.
You let yourself drift down to the bottom of the pool. You feel your feet touch the tiles. Then, gently, you push off with your toes, glide up to the surface, take a single breath, and let yourself sink again. You repeat the cycle for as long as it takes. The men and women who pass are not stronger than the ones who fail. They are not fitter. They are not braver. They have simply learned the one thing the others haven’t: the way out is not the way you think.
Everything in them wanted to fight the water. The training was teaching them to trust it.
I think most of us are drowning in pools we could be floating in. We are pushing at doors that open by pulling. We are fighting our way through a situation that a single new thought — the right new thought — would resolve almost immediately. We were never as trapped as we felt. We just hadn’t learned how the handle works.
You can spend a lifetime banging on a door that was never locked.
This is why renewing the mind is not a nice optional extra for the spiritually keen. It is essential. It is the difference between drowning and floating. It is the difference between a small life and a free one.

Comfort in the familiar
The old mindset, awkwardly, is often the most comfortable one.
It is like the favourite old jumper or the joggers you’ve had since university. They are soft. They are familiar. They smell of you. They may have holes in them, they may be fraying at the cuffs, your spouse may have been quietly trying to throw them away for years — but they fit. You like how they feel.
Your old mindset is the same. It has been processed, shaped and lived in for years, sometimes decades, sometimes for generations before you ever inherited it. It may be full of dysfunction. But to you, it doesn’t feeldysfunctional. It feels normal. That is what makes it so dangerous. Dysfunction that feels normal is the hardest kind to escape, because you cannot see it.
Even when it limits you, the old mindset offers a strange, false security. Changing it feels like effort. Beginning to think differently feels like breaking in a stiff new pair of shoes — they pinch, they rub, they don’t yet fit the shape of your foot. And if we are honest, a great many people don’t change simply because staying the same is easier than transforming.
But here is the good news, and I want you to take this in slowly: you are not stuck with your current mindset.
Transformation does not happen all at once. It almost never does. But it begins the moment you become willing to challenge your thinking. You do not need to have it all figured out before you start. You do not need a five-step plan. You do not need to feel confident. You simply need to believe there is more, and that your thoughts do not have to be permanent.
*
Lean into the discomfort
I have to tell you, before we go any further, that this part is uncomfortable. There is no way around it.
A renewed mind cannot be built on the foundation of an unexamined heart, and examining your own heart is, frankly, one of the hardest things a human being ever has to do. It requires vulnerability — and not the curated, social-media kind. The real kind. The kind that admits, yes, that wound is still there. Yes, I am still angry about that. Yes, I still flinch when I think about her. Yes, I am still afraid of being seen. Yes, I have been pretending I’m over it.
It requires humility — the willingness to say I might have been wrong. About yourself. About your story. About the people who hurt you. About God. About what you deserve. About what is possible.
This is the part where, in my experience, most people stop. They get to the edge of the discomfort and they back away from it. They sense the cost and they decide the prison is, after all, preferable to the work of getting out.
I want to plead with you: don’t.
Lean into the discomfort. Don’t run from it. Don’t numb it. Don’t argue it away. The thing in you that is most resistant to being looked at is almost always the thing most desperately in need of being looked at. The vulnerability you are avoiding is the doorway. The humility you are flinching from is the key.
You will not be punished for the honesty. You will be set free by it.
The Bible puts it this way: God resists the proud, but gives grace to the humble (James 4:6). I have come to read that verse less as a threat and more as a piece of practical theology. Pride keeps the door locked. Humility opens it. There is no transformation without humility, because there is no transformation without the willingness to admit that the way you have been thinking is not the way you were made to think.
The new mindset will feel stiff at first. It will require honesty. It may bring tears. It may bring an apology you’ve been avoiding for years. But it will lead you to open doors you didn’t know were there. You will begin to see things you have never seen before — opportunities, relationships, ideas, vision, callings, possibilities.
That is the power of a renewed mind.
And it is closer than you think.

Personal reflection
• What old beliefs or mindsets have shaped how you see the world?
• Can you trace any of these beliefs back to a particular event, person or family pattern?
• Who told you that? What is one limiting thought you carry that, if you traced it honestly, came from someone else’s voice rather than your own?
• What have you assumed was impossible that might actually be possible if your mindset changed?
• Where in your life have you been pushing at a door that opens by pulling?
• What is the area of your thinking that you have been most reluctant to examine? Why?
Declaration
I am not trapped by my past, my patterns or my pain. By God’s grace, I am free to renew my mind, to take responsibility for the way I think, to lean into vulnerability and humility, and to see the world — and myself — through new eyes.
