learn one's lesson

Heed past mistakes

To learn one's lesson is to gain wisdom from a negative experience, typically by suffering consequences that discourage repeating a mistake: After getting food poisoning from that restaurant, I learned my lesson.

The phrase implies the understanding came through hardship rather than instruction.

Someone who hasn't learned their lesson keeps making the same error.
