If you are disappointed because you can’t be the best person to do everything yourself, you are terribly naive. Nobody can do everything well. Would you want to have Einstein on your basketball team? When he fails to dribble and shoot well, would you think badly of him? Should he feel humiliated? Imagine all the areas in which Einstein was incompetent, and imagine how hard he struggled to excel even in the areas in which he was the best in the world.
