I first wrote them starting from Search for the Truth. Then I found what they were standing on.

Read them in order. Each one builds on the one before it. You start at the centre, where nobody's watching, and work outward to the part people actually see. So don't skip to the ones that appeal to you.

After each one, use what you've learnt. Just one thing you need to improve on. It doesn't have to be big.

Core: Build your worth

The part no one sees. Truth you found yourself, skills you paid for in effort, habits nobody claps for.

1. Build Your Worth in the Dark

The habits no one sees are the ones that build you.

At the start of Year 9 I began praying every night without missing a single day. Fifteen minutes a night, and within 24 days I could say the full prayer.

It was stacking up. I didn't know it. I was happy I wasn't aware, and that's what kept me consistent: I was doing it to fix myself, not for a reward. Every day I prayed, I was changing the direction of my life by the slightest. I can't say it was a sudden miracle, that one day I woke up a new person. It was gradual.

All the high-performing people and I have one thing in common: we kept a habit going without approval until it compounded into a result you could see. You don't ask anyone to start. You don't tell anyone.

In 1973, a group of preschoolers were split in two. One group was rewarded for every drawing they made, and the other drew for fun. Over the weeks, the rewarded group drew fewer pictures. The reward had turned play into work.

Goals are “how can I get there?” Purpose is “why should I do this?” I couldn't work out the why at first, so I kept doing the habit until I did. The one thing that finds your purpose is the act of acting.

How it started

2. Endure the Unseen with a Purpose

Pressure gets you started. Purpose keeps you going when you can't see results.

At the start of the year I set a goal to gain weight, so I started going to the gym. My pressure came from the people who had called me “skinny” and “a twig.” I didn't want that label. I wanted to be seen as a leader.

I pushed the 10kg dumbbells up with all the energy I had left. “Last rep,” I told myself.

One more.

The weight was halfway up. I looked back. No spotter. There was no one to help me.

It didn't move. I pushed harder. Millimetres of movement.

Then I readjusted my position and gave it my last sudden burst. Closer. Close. And it was fully up.

Then I brought it back down, slowly, under control. This was only one of hundreds I would do alone.

My gym journey had just begun. Two weeks in, I'd built the habit of going, and I had no progress. In the mirror my arms looked the same. I still wanted to quit.

People quit because they don't have pressure strong enough to keep them going. In the three weeks of school holidays, a friend and I both committed to going every weekday. He went every day of the first week. In the second he slept in one day and fell away from there. By the third he was completely inconsistent. He had a goal but no pressure. I went when I didn't want to go. He went when he wanted to.

A goal is the outcome you want. A standard is the least you expect of yourself, like stretching every time you work out, and it never gets skipped. The goal gets you moving, and the pressure keeps you going.

On my Year 9 camp I chose the hardest option: tents every night and the full hike. It was my first time hiking, with 15kg on my back. Then came the hardest turn of my life.

It was about 3 centimetres wide, and right beside it was a 50‑metre fall straight into the river. If I lost my balance, my pack would pull me straight into the drop. I hugged the tree on the other side and shuffled through.

After two hours we made it. That night a thunderstorm hit, and we chopped dinner on a board that had been dropped in the mud. My family had asked why I didn't choose the easier option. I had a purpose: to come out of that camp more skilful, by building skills through the pain.

We didn't wish for food, and we didn't wish for a sunset. They came to us.

3. Search for the Truth

Your truth only forms under your own experience, not someone else's.

Before I started high school, I asked some older friends if it was hard. “Nah, it's quite easy.” “You'll be alright.” My parents said yes.

On my first day I stood still in the hallway, trying to work out where room A1 was.

It was tricky at first, and the more I experienced it, the more I enjoyed it.

Once a belief is formed, your mind looks for evidence to prove it right. When elephants are young, trainers tie them to a pole with a rope, and they struggle to get free. By the time they're strong enough to break it, they believe they can't, so they stay put on a one-inch rope.

Go and find out for yourself. What you've lived through is worth more than what you've been told. This one is the free chapter.

4. You Can't Buy Everything

Integrity, work ethic and resilience can only be earned.

Near the end of Year 8 we had a big English essay exam, and we were given the question beforehand. Many of my classmates wrote the essay at home and copied it into the exam, some off their smartwatches. One printed his and was caught halfway through. I didn't cheat. The people who cheated did worse than the people who didn't, and I got one of the highest results in the class.

In a five-person STEM project, most of my group stopped contributing, so I built our website myself. I spent so long on it that I ran out of time for the written part, which was marked on its own, and got 75%. But I learnt how to design a website, a skill that will stay with me for life.

You can buy books, you can buy new technology, and you can buy the best resources. They won't make a difference unless you have the five core skills.

  • Integrity
  • Work ethic
  • Resilience
  • Teamwork
  • Self-awareness

You pay for them in effort, and no shortcut ends with you actually having them.

5. Only Learn What You Don't Know

Life is short. Find the gaps you can't see, and fix those.

Life is short.

We think we're living in the present, but the future is only seconds away.

Many waste their lives trying to look better than their peers. Many waste their lives looking down at the poor. Many waste their lives arguing over little things. Many waste their lives putting others down. Many waste their lives thinking and not doing. I can fill this whole chapter with this list.

Many simply don't know what they're doing. They need awareness.

In 2008, Kobe Bryant lost the NBA Finals to the Boston Celtics, four games to two. That summer he went to the film room and watched replays of his games, looking for the gaps Boston had exploited. He watched to understand the game, not to relive the pain. The following year the Lakers won the championship, and the year after that.

If we can't see it, how can we change it? In Year 9 I prepared for an English essay by having AI write practice questions, and in the exam I wrote a well-structured essay. It got a failing grade. The feedback said I hadn't clearly addressed the question. You can put a lot of effort into a skill and still be way off where you meant to go.

Feedback keeps you on the right path. Not knowing where and how you're wrong is the weight that holds you back.

6. Become the Teacher

Once you teach it, you master it.

The ones who teach benefit from the ones who learn. Once you become the teacher, you become the master of what you teach.

While I was writing this chapter, I started writing articles on my main ideas. Teaching what I'd found helped me keep it.

Gain the knowledge, apply it, then teach it. Use the Feynman Technique and explain it simply to someone else. You find the holes in what you know the moment you try.

Mantle: Use your worth (being written)

Where the worth starts moving. Once I'd built my foundation, real changes started happening. The Mantle is about using what you've built, and that takes effort and strategy.

My third try at Year 10 Student Leader.

Crust:

Selected.

I felt upset.

The destination came too quickly. My vision was limited by my thinking.

Mantle:

Generosity and kindness, to build trust and stronger connections.

Core:

I shifted my mindset: this was a role full of experience, not authority.

That’s where the three layers came from.

Most stories show you the achievement and the effort, but not how it was done. Mine didn't either. The how is this layer, and I'm writing it.

Crust: Turn worth into meaning (being written)

The only layer anyone else sees. This is where worth turns into meaning, by being spent on someone other than you.

At a school musical I was an usher. Two other student leaders greeted everyone at the gate, while I stood there in my suit and shiny badge doing literally nothing. Then I was told to walk down to the other gate. I could have said no. I went, knowing I'd be on my own.

To every single person: “Good evening, how are you?”

Little hope was left. I was about to walk back to the group.

Then someone I knew, who was helping, pulled up right in front of me. I asked him to stay and help.

“How’s your book going?”

That was Max. In one day I built a deeper connection with him than with friends I'd been around for three years.

He had started a business a few months before and had just hired his first employee, at 18. A whole employee? I'd seen so many videos of teenagers getting rich, and that day the pressure to be like them only got stronger.

Become like the rich kids on YouTube.

I went home that day and researched businesses to start, and I spent my lunchtimes calling vet clinics to sell them AI automation. The first recording I took starts with me asking, “So, how do I even introduce myself?” After the fifth call I realised they didn't need it. They'd been pitched hundreds of ideas like mine, by people with far more experience.

Change someone’s life.

I was at my desk when I decided to use what I'm good at, thinking deeply and helping people. That's this book.

“How’s your book going?”

The next practice, Become Understood, is the one I’m writing now.

Dear 15,
