You build on failure. You use it as a stepping stone. Close the door on the past. You don't forget the mistakes, but you don't dwell on then either. You don't let it have any of your energy, or any of your time, or any of your space. Always have faith in yourself no matter what, sometimes you are your best bet, just don't be shy to go all in because you know your worth it and there is nothing stopping you from winning besides yourself.
