Chess players get better by studying their losses, not framing their wins.

A win tells you the whole thing worked well enough, which is almost no information. A loss points directly at the move where your thinking broke, and that specificity is why it is worth more. It is also why so few people do it, since going back over a defeat means living in it slightly longer than you want to.

After the next thing that does not go your way, do a short review while it is fresh. Find the single decision you would take back and name what you were thinking at the time. One loss examined properly is worth ten shrugged off.
