Proper proverb?

[tsien]

Hello!

Say I made a stupid mistake before, next time in a similar situation I find myself smart enough not to do it again. Is there an English proverb or idiomatic expression to describe what I just mentioned?

Thanks in advance.

Fool me once, shame on you. Fool me twice shame on me.
Dont know if it applies to what you are saying though.
