" When someone is told over and over again that he’s no good at something, he loses more and more confidence and eventually does become poor at it. Conversely, if he’s told he’s good at something, his confidence builds and he actually becomes better at it. While a person is born with strengths and weaknesses as part of his heredity, they can be greatly altered by later influences. "
