Sadly your being sarcastic.. 
do you think that anyone ever got anywhere without first believing in themselves? There is only one logical way of thinking and that is to be self-assured, so long as there is adequate thought and reaosn put into ones opinions.
You're changing the course of discussion - this isn't what we were arguing about before. You made the erroneous statement that 99.9% of humans are identical to each other simply because 99.9% of our genetic makeup is the same, while ignoring the fact that that 0.1% difference is responsible for Pygmies on one end and NBA giants on the other, morons on one end and geniuses on the other, and so on.
You couldn't refute my statement about the bell shaped distribution of human traits and so, suddenly started talking about heart and will, saying that that's all it takes to achieve anything. As I mentioned before, heart and will plays a role, but only if someone has the capacity to achieve something in the first place and puts in the needed work, while having a good game plan.
A 4 foot pygmy can have all the heart and will in the world, but will never become the best player in the NBA. Same reason why guys like Mike Arvilla will never get a pro card no matter how hard they try or how passionate they are. It's all about genetics first and foremost. Chris Lund once said that if you combine Rich Gaspari's work ethics and will with Flex Wheeler's genetics, you'd get an unbeatable bodybuilder. Ask yourself why that should be, when according to you, all Rich Gaspari had to do was "will" his way into having rounder muscles and a better frame than Flex Wheeler.
