There are few who can implement those things they understand, for 12 hours a day, with 4 hours sleep most nights, no holidays, no weekends, and often, initially at least, with no garuante of success and little recognition, for years.
But the ability to do those things, coupled with a natural intelligence (regardless of some IQ score), is what differentiates a truly successful person.
At least based on the ones I know.
IMO the only way to be able to do that, is to truly have vision you are 100% sure of, to raise "mind above matter" and do the physically/mentally impossible.
A certain role model of mine once told me a great phrase: "I'll give you 5 cents for a great idea, $1 million for a great implementation".
