10% talent and 90%

A person with 10% talent and 90% belief in what the talent can do accomplishes alot more that a man with 90% talent and 10% belief in what that talent can achieve. 

David only had a stone and a sling but the level of belief he had was way up in the sky in the end he slayed a giant, trained, professional soldier. So believe in the little you have at your disposal and you will accomplish alot.
