or not learning from your mistakes.

thanks.

OP, the idiom you might be looking for could be khet laap = to profit from experience, to be wary of a previous bad experience and not wanting to repeat it. Just use the negative mai before that phrase to indicate that someone hasn't learnt from a previous experience.

There's another similar idiom which is laap jam meaning to have learnt one's lesson and not wishing to repeat it (or insert the negative again using mai). My Thai gf tells me this is less commonly used though.
