Here you use a great word thoughts of past mistakes.

It's really a great thinking we have to thinking about our past in every step of life, if we are going to do something we have to have some previous experience on it and experience is the word that's meaning a lot. What we do in our past it's could not be experience all the time, experience is the word that mean for doing something accurately because we just thought about our past and identify what was the mistakes are done by us, recovering those mistake doing something properly it experience.

Thank you for your great one.
