A few months ago, I finished a book by Robert Greene called "Mastery". In it, Mr. Greene told the stories of people who had risen to the top of their fields, and explained what it took for them to get there.
No matter what field the masters were in, art, science, business, etc..., the basic formula was the same. Tenacity, creativity, and passion got all of them to the top. I have a long way to go, but I'm on the right path.
