There comes a point when you have to stop beating yourself up over mistakes that you made. The mistakes that you have made in your past, should be left in your past. Forgive yourself for your faults and move on. Your mistakes should be your motivation, not your excuses. It's amazing how much more you can learn by making mistakes than you can by making perfect decisions. Mistakes are a part of being human. Appreciate your mistakes for what they are: precious life lessons that can only be learned the hard way.
