I don’t know if I continue, even today, always liking myself. But what I learned to do many years ago was to forgive myself. It is very important for every human being to forgive herself or himself because if you live, you will make mistakes. It is inevitable. But once you do and you see the mistake, then you forgive yourself and say, “Well, if I’d known better I’d have done better,” that’s all. So you say to yourself, “I’m sorry.”

If we all hold onto the mistake, we can’t see our own glory in the mirror because we have the mistake between our faces and the mirror. We can’t see what we’re capable of being. You can ask forgiveness of others, but in the end the real forgiveness is in one’s own self. The real difficulty is to overcome how you think about yourself. If we don’t have that we never grow, we never learn, and sure as hell, we should never teach.
-Maya Angelou
