Sir Godfrey Gregg 

Everyone, at some point in their life, is going to make a mistake, in fact, many of you probably already have. Unfortunately, there is no fix for mistakes, no going back, no changing the past. There is only moving on and forgiving yourself.

Take with you the lessons from your mistakes and live well knowing that you have made the best of the situation, you have learned, you have grown.

If you grow after a mistake, it is no longer a mistake but rather a helpful pointer telling you to try again a different way. Forgive yourself, you are trying your best.
