Don’t over-think about mistakes you made, Just focus on the right side.
Focus on learning how to not repeat mistakes.
George Bernard Shaw says:
A life spent making mistakes is not only more honorable, but more useful than a life spent doing nothing.
If you are going forward and doing what you think is right, don’t blame yourself that much.
I don’t say you don’t have to think about mistakes, I mean you have to know that you have done wrong and then, the most important issue is, not to repeating them.
And, at the end:
Try doing anything you think is right, and if you did right, make it better for the next time, and if you did wrong learn something from it 🙂
Over-Thinking is Forbidden.
