Have you learned your lesson will you make different choices when you get out?

Speaking as a former inmate, I can say that "I've learned my lesson and I am very aware that the decisions facing me going forward will be made with a lot of contemplation about potential consequences." This was an expensive lesson for me, as time and money were wasted. I'm hoping that my recollection of being locked up is enough to make sure that all my decisions are good ones.
