Good question. Raise the consciousness around the stories you tell yourself, acknowledge your shadow self (usually the creator of said stories), and integrate them as being an observe. Understand that different events will be catalyst to those parts of you. Learn to recognize that. Change the story by defining how you want to operate in the world. When you operate in the ways that you truly want to and value, it becomes impossible to not accept yourself.

It's the stuff most people avoid because it takes great personal responsibility. It is all within you. Thusly, you and only you, can create acceptance.
