You can’t learn from a mistake you’ve decided wasn’t yours.

Learning needs an owner. The lesson sits inside the part you controlled, so the moment the error is placed elsewhere, the whole thing becomes somebody else’s homework and you walk away with nothing. It can even be mostly true that it was not your fault and the result is the same, because true and useful are different tests.

Find your share, however small, in whatever went wrong most recently. Say what you would do differently in that same situation. One sentence of that beats a correct account of who was responsible.
