Why drawdowns are harder to recover than they look
Gain needed to recover = drawdown ÷ (1 − drawdown). A 10% loss needs an 11.1% gain to get back to even, 25% needs 33.3%, and 50% needs 100%.
Because the recovery has to be earned on a smaller account, every extra percent of drawdown gets more expensive. Keeping drawdowns small matters more than finding bigger winners.

Losing streaks are normal
Even a good strategy has long losing streaks. With a 50% win rate, the chance of at least one streak of 6 losses in a row within 100 trades is about 55% — more likely than not. Knowing that in advance makes it easier to keep following your plan — and to size positions so a normal streak can't do serious damage.
