It depends on the criticism If it's invalid criticism: If it's from someone whose criticism matters: pursue the criticism and reach the truth through reasoning If it's from someone who doesn't matter: ignore, make stuff If it's valid criticism: You learned something. You could have continued doing things the wrong way and been worse off for it. You are in a position where someone cares enough to look at your work and take time to give you feedback.
