Furthermore, once you assume that something is innate, it automatically becomes something you can’t do anything about: If you don’t have innate musical talent, forget about ever being a good musician. If you don’t have enough willpower, forget about ever taking on something that will require a great deal of hard work. This sort of circular thinking—“The fact that I couldn’t keep practicing indicates that I don’t have enough willpower, which explains why I couldn’t keep practicing”—is worse than useless; it is damaging in that it can convince people that they might as well not even try.
