Mistakes of the past
The past wouldn't be possible without the existence of the present, and the present wouldn't be possible without the existence of the future! But often, the future is better because of the mistakes of the past! So, let the mistakes of the past guide you on the path to a better future! (And remember that bad things can be used in two ways...1 destructively, if you let them bring you down, or constructively, if you use them to your advantage.)
