Successful people often insist that their success was not random, and attribute it to some specific quality (persistence, courage, the capacity to be alone, etc.) even though there are tons of other people who had the same quality and still failed to be successful. It's fundamentally difficult for us to accept the fact that even Shakespeare wouldn't be able to teach us how to "unleash our inner Shakespeare", and that most people who want to be special will never get what they want.
