Some of your wins were luck. Admitting it makes you sharper, not smaller.

Good outcomes get absorbed into a story about your own ability, because that version is more pleasant and harder to check. Some of them involved an easy draw, a kind marker, a question you happened to have revised the night before. Counting those honestly does not take the result away. It tells you which parts you can expect to repeat.

Look at a recent success and separate what you did from what went your way. Then ask what would have happened with ordinary luck. The answer usually points at one thing worth shoring up.
