I feel there is a common trait of extraordinary people that anyone can develop and it pays dividends. That trait is industriousness. When you listen to interviews from successful people like Elon Musk all the way through to Arnold Schwarzenegger, they all talk about working hard.

Terry Toa almost failed the general exams at Princeton due to slacking off, and it was a valuable lesson for him. I don't care how gifted you are, you won't reach the top without working harder than others.
