Train the mind
the way you train the body.

One hour. No phone, no speech, no input. Sit with your own signal and observe what surfaces.

Make one decision you've avoided for over a week. No deliberation. Commit before the timer ends.

Choose the hardest task on your list. Ninety uninterrupted minutes. Nothing else exists.

Write the opposite of what you believe about your current problem. Defend it for twenty minutes.

Ask one person for something that scares you. Direct, specific, unhedged. Accept any answer.

Identify one commitment, habit, or belief that no longer serves you. Remove it today.

Marcus Aurelius's daily reckoning. Write what you'd cut from today's calendar if it were your last. Then cut it.

Buffett's lens. List the three domains where you actually have edge. Decline every decision today that lives outside them.

Kahneman's move. Assume your current project failed in a year. Write the autopsy now — and act on the top cause today.

Seneca's hour. Walk alone, no input. Rehearse losing the thing you fear losing most. Return and decide what it changes.

Identify one action today that compounds — code, content, capital, or judgment. Spend the hour only on that.

Jobs's discipline. Pick one constraint everyone treats as fixed. Argue, on paper, why it isn't. Then move as if it isn't.
