I call them lessons learned. I don't regret anything, because I always make sure that I am okay with that decision and the consequences of it. I believe that in life, you learn many lessons, but you never try to hurt people or yourself on purpose
The Worst Mistake You Can Make Is To Walk Away From The Person Who Actually Stood There And Waited For You. So decide wisely especially when you are given a second chance as once gone it is gone forever, and your attempts will be too late.
