Compassion for yourself when you fail means you don't need to be a delusional jerk to succeed and you don't have to feel incompetent to improve. You get off the yo-yo experience of absurd expectations and beating yourself up when you don't meet them. You stop lying to yourself that you're so awesome. Instead, you focus on forgiving yourself when you're not.
