This is a pretty interesting article on Mark Zuckerberg’s ingredients for success: Ambition, Vision, Execution, Determination, Luck, and Timing.
I love this quote from President Calvin Coolidge:
Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination are omnipotent. The slogan ‘press on’ has solved and always will solve the problems of the human race.
