Being social beings, our need for the company of other human beings is valid, a very part of the innate design. But having to seek validation from others is not.
We were designed to be our own cheerleaders, our own champions. Until we fell from grace. Since then, we seek validation from the outside, love from the outside, acknowledgement from the outside.
Life however ensures that we do not succeed at this quest. How else would we be forced to reconsider the presence of that inner cheerleader? Once we fall back upon our only dependable friend – our own inner self, the social scene starts re-orienting. After all, you were rejected by others only so that you re-unite with yourself. If and when this happens, life is happy to turn around your social scene.
