Assert your right to make a few mistakes. If people can't accept your imperfections, that's their fault. — Dr. David M. Burns. American professor of psychiatry Mistakes, Perfection
Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make you a far happier and more productive person.
Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life.
