Perfection' is man's ultimate illusion. It simply doesn't exist in the universe.... If you are a perfectionist, you are guaranteed to be a loser in whatever you do.

Don't apologize for what you think you did wrong. Apologize for what they think you did wrong.

Guilt is not the best way to remedy your mistakes.
