Dostoyevsky writes: The greatest punishment for a man is to be imprisoned in his past. Every time you say (if I didn't do that...), you pay the price of the past. The truth is that the past is a debt that never settles; The more you think about him, the more he eats up your portion today.
The only way to deal with the past is to declare bankruptcy:.
Admit that that version of you made a mistake, pay the price and close the case.
