I also agree with you past mistakes guide me. Every people make mistakes and this mistakes guide us to make perfect. If i go to a job but made mistakes and i have to find out what was wrong with me ,then next time when i will go to another job ,that time i will not make same mistake and maybe i can do better things. In my opinion mistakes is a experience but not lots of mistakes, if i do again and again my life will be ruined. Thanks to share your valuable post.
