When our self worth is staggeringly lower than it should be, we will go out of our way to prove our worthiness by trying to please others, help them, care for them or worse yet, try to fix their problems. Anything to get validation will suffice. But our true worth will never be filled up in soul satisfying ways until we begin to glean our validation from within.
The only validation we will ever truly succeed in garnering is our own. And we will not feel worthy of any such validation until we turn to the true source, God.
