Think Like Poker Players

An edge only pays off for players who are still at the table — so the first rule of risk is to stay in the game.

A strategy with positive expected value can still end in ruin if each bet is too large for the reserves behind it. Bankroll management sizes every risk so that a bad run is survivable, which is why disciplined professionals often bet smaller than their confidence suggests.

Tilt rarely looks like rage. It looks like a quiet shift in your criteria that you never decided to make.

Emotion after a loss or an insult doesn't announce itself; it lowers your standards, widens the hands you play, and makes the next bet feel justified. Professionals manage tilt by watching their own decision rules for drift — the same discipline that protects judgment in boardrooms, trading floors, and family arguments.
