We may attempt to prove ourselves and our worth in many ways. Needing to prove ourselves can be insidious as we strive to be accepted. This is a basic human need.
When you accept that you are complete and whole, that you are not lacking in any way, you stop looking outside yourself for something or someone to complete you. When you look outside yourself for validation of how you should be or act, you actually give your power away to some external person or thing! It is YOU who requires your approval and consideration. You cannot find what you are looking for in something outside of you. You cannot buy enough stuff to make you happy; there will always be a longing for something more.
You don’t need to prove anything to anyone. You are whole and complete and wonderful.
