Mindsets are beliefs—beliefs about yourself and your most basic qualities. Think about your intelligence, your talents, your personality. Are these qualities simply fixed traits, carved in stone and that’s that? Or are they things you can cultivate throughout your life?

People with a fixed mindset believe that their traits are just givens. They have a certain amount of brains and talent and nothing can change that. If they have a lot, they’re all set, but if they don’t... So people in this mindset worry about their traits and how adequate they are. They have something to prove to themselves and others.

People with a growth mindset, on the other hand, see their qualities as things that can be developed through their dedication and effort. Sure they’re happy if they’re brainy or talented, but that’s just the starting point. They understand that no one has ever accomplished great things—not Mozart, Darwin, or Michael Jordan—without years of passionate practice and learning. - from Carol S. Dweck, Ph.D. - Author of "mindset".
