> Purposely believing in something that you know is most likely to be incorrect This makes me think of: acting. One way to act like a character is to try to believe you are that character. Or to believe everything the character believes. Then you figure out the detailed implications: when you see x, you think y, so you feel z (which should show on your face and body language) and do w. One way of finding the implications is to physically put yourself through experiences your character has had; if that is impractical, you can look for substitutes. (There is a famous story[1] of an actor who gave a compelling performance of a character agonizing over killing himself with a revolver in his hand... by imagining he was about to take a very cold shower.) Which then brings to mind an approach: imagine you are the person you would like to be, imagine how that person would act, and act that way. (I'm not sure whether, to the parent commenter, that would be "a greatly successful person in the early stages" or "a person who will do the best he can—choosing the strategies with highest expected value—knowing bad luck may crush his efforts in the small or in the large, and won't be bothered if/when that happens because his choices were still the best".)
