CAPABLE UNDER PRESSURE one at a time, in the open

Build one million more capable humans.

Self-defense, human performance, systems thinking, AI, and the lessons of space — turned into people who can protect themselves, perform, and provide, and stay sharp under pressure. I build the work in the open, then hand it to you.

THREE PATHS

One question, three ways in: what makes a human harder to break?

P-01

Protect Yourself

Handle yourself, anywhere.

Real, pressure-tested self-defense for ordinary adults — not choreography. The Self Defense 4 All method: show up, get trained, walk out more dangerous to the thing that scares you.

P-02

Build Capability

Perform — and provide.

Capability isn't only physical. Performance you can measure — strength, recovery, aging on your terms — and the ability to earn: build a business, learn to sell, never depend on a single paycheck. The systems that keep you standing when a job or a market gives out.

P-03

Explore the Frontier

Where capability meets the edge.

Space, AI, and the discipline of telling footprint from reality. Building GForce in the open — audits, hardware, and the return to the frontier I came from.

THE WORK IS OPEN

I don't make content. I do the work — and show it.

Free comes first. The classes, the experiments, the builds, the failures — turned outward so anyone can use them. The offers come later; the giving is the point now.

  • FIELD NOTESThe newsletter. What I'm learning across the mat, the body, the systems, and the frontier — in writing, weekly-ish.
  • THE SHOWThe podcast. Real conversations and out-loud thinking — the frontier read through the eyes of someone using it.
  • BUILD IN PUBLICWhat I'm building. Studio tools, training systems, AI agents — shown as they're made, not after they're polished.
  • THE VAULTThe show's memory, open. The companies, people and questions the show keeps returning to, as a graph — and every idea, kept, with the cheapest experiment that would test it. Open the vault →
  • TOOLSThings you can use. Protocols, checklists, and small tools handed over free — capability you can pick up today.
THE OPERATOR'S VIEW

They read the frontier from abundance. I read it from the chair where the bills are due.

Every Friday I take the week's frontier conversation — the one everybody's already hearing — and work out what it actually means for someone running a real business. Not analysis. Translation.

The Operator's View episode 1 — I can't influence China

No. 001

I can’t influence China. I can influence my day.

NVIDIA posts a $96.2 billion quarter and the panel discusses it from a position of capital abundance. I listened to it while making sure the ads work, the offer converts and the bills get paid. Where I landed: read the filings, not the feed — and stop spending yourself on the things you cannot move.

THE ROOM

Capable people, together.

The work is better with people on the same line. As the field notes go out and the builds ship, a room forms around them — people getting harder to knock down in the body, in the work, and at the frontier. Come in early, while it's small.
