The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

If you can understand just one thing thoroughly, then you will understand everything.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

Do what you have always done and you will always be what you have always been
