Every death is a free lesson — it's the game telling you exactly where a decision went wrong. Reviewing deaths is the fastest, most concrete way to climb, because the fix is almost always a rule you can follow next game.
A death is unambiguous — you either had to die or you didn't. Unlike vague "macro" feelings, each one has a clear cause you can name and a clear fix you can apply. Review your deaths and your deaths-per-game drops; that alone wins games.

The killing blow is rarely the mistake — it's the last domino. Look earlier:
Convert the mistake into a rule you can actually follow. "Don't int" isn't a rule; these are:
