Reflections on health, fitness and quality of life
2025 review - health & fitness

The most surprising thing I’ve learned about health and fitness this year shouldn’t be surprising at all.

Training plans work. You just have to actually follow them.

Historically, that’s been my problem.

I’ve always been deeply competitive with myself. If I showed up to a session (especially something hard) I felt like I owed it everything. If I went out for a run and wasn’t dying at the end, then what was the point? Had I really done anything at all?

Effort was the point. Exhaustion was the receipt.

What’s changed isn’t my interest in running or fitness - it’s my relationship to restraint. For the first time, I’m following an actual plan. And for the first time, I’m listening when the plan tells me to hold back.

Having recruited ChatGPT as a coach, having it explicitly shame me and say, No — recovery matters. Getting a light run tomorrow is more important than destroying yourself today, has been a genuine game-changer. Not because it’s novel advice, but because I finally stopped negotiating with it.

Restraint, it turns out, is the name of the game.

The cliché is that life is a marathon, not a sprint. I’ve heard it a thousand times, nodded along, and then maybe dialled it back to 95% (for three days). But actually training for a marathon forces the metaphor to become real. You start to understand that pacing isn’t a nice-to-have… it’s everything.

Sure, if you reaching the fine stretch and you’ve still got something in the tank, go for it. That’s earned. But the sensible thing, the thing that actually works, is the negative split - finishing stronger than you started. You don’t prove anything by going out too hard early. You just make the rest of the race harder than it needs to be (and risk exploding along the way).

Once you see that clearly in your body, it starts bleeding into everything else.

I’ve started thinking about my relationship with my wife differently. Not as chapters to grind through or months to survive, but as seasons in a much longer game.

The goal isn’t to “win”.
The goal is to keep playing the game.
Forever.
An infinite game.

The same shift has shown up in my work. I’m learning (slowly and imperfectly) that applying attention in the right places matters far more than overcommitting everywhere. Chipping away, every damn day, at the boring things builds steady progress against the plan. Scatter-shotting in every direction and calling it ambition, does not.

Heroic effort is seductive. Consistency is effective.

We tell our kids the story of the tortoise and the hare, as if it’s some quaint moral fable. Go slow to go fast. Don’t burn out. Be patient. It turns out, the lesson doesn’t get easier with age, ignoring it just gets more expensive.

I don’t have a dramatic conclusion here. No transformation montage. No final boss defeated.

Just this:
The work is the work.
And the work speaks for itself.

If you can put aside the need to empty the tank every day - in training, in relationships, in life - and focus instead on pacing well enough to keep going, everything gets better.

Not all at once. But one day you look back and realize how far you’ve come.

What distinguishes you from other developers?

I've built data pipelines across 3 continents at petabyte scales, for over 15 years. But the data doesn't matter if we don't solve the human problems first - an AI solution that nobody uses is worthless.

Are the robots going to kill us all?

Not any time soon. At least not in the way that you've got imagined thanks to the Terminator movies. Sure somebody with a DARPA grant is always going to strap a knife/gun/flamethrower on the side of a robot - but just like in Dr.Who - right now, that robot will struggle to even get out of the room, let alone up some stairs.

But AI is going to steal my job, right?

A year ago, the whole world was convinced that AI was going to steal their job. Now, the reality is that most people are thinking 'I wish this POC at work would go a bit faster to scan these PDFs'.

When am I going to get my self-driving car?

Humans are complicated. If we invented driving today - there's NO WAY IN HELL we'd let humans do it. They get distracted. They text their friends. They drink. They make mistakes. But the reality is, all of our streets, cities (and even legal systems) have been built around these limitations. It would be surprisingly easy to build self-driving cars if there were no humans on the road. But today no one wants to take liability. If a self-driving company kills someone, who's responsible? The manufacturer? The insurance company? The software developer?
