All of these people had character. None of them thought they were special people, born with the right to win. They were people who worked hard, who learned how to keep their focus under pressure, and who stretched beyond their ordinary abilities when they had to.

When you enter a mindset, you enter a new world. In one world--the world of fixed traits--success is about proving you're smart or talented. Validating yourself. In the other--the world of changing qualities--it's about stretching yourself to learn something new. Developing yourself.

In the fixed mindset, everything is about the outcome. If you fail—or if you’re not the best—it’s all been wasted. The growth mindset allows people to value what they’re doing regardless of the outcome . They’re tackling problems, charting new courses, working on important issues. Maybe they haven’t found the cure for cancer, but the search was deeply meaningful.

In fact, in the fixed mindset, adolescence is one big test. Am I smart or dumb? Am I good-looking or ugly? Am I cool or nerdy? Am I a winner or a loser? And in the fixed mindset, a loser is forever.

The idea that one evaluation can measure you forever is what creates the urgency for those with the fixed mindset. That’s why they must succeed perfectly and immediately. Who can afford the luxury of trying to grow when everything is on the line right now?

But if your claim to fame is not having any deficiencies - if you’re considered a genius, a talent, or a natural - then you have a lot to lose. Effort can reduce you.
