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

it’s not always the people who start out the smartest who end up the smartest.

In this book, you’ll learn how a simple belief about yourself—a belief we discovered in our research—guides a large part of your life. In fact, it permeates every part of your life.

Much of what you think of as your personality actually grows out of this “mindset.” Much of what may be preventing you from fulfilling your potential grows out of it

No book has ever explained this mindset and shown people how to make use of it in their lives. You’ll suddenly understand the greats—in the sciences and arts, in sports, and in business—and the would-have-beens. You’ll understand your mate, your boss, your friends, your kids. You’ll see how to unleash your potential—and your children’s

Yes, a whole organization can have a mindset

Robert Sternberg, the present-day guru of intelligence, writes that the major factor in whether people achieve expertise “is not some fixed prior ability, but purposeful engagement.” Or, as his forerunner Binet recognized, it’s not always the people who start out the smartest who end up the smartest.

Believing that your qualities are carved in stone—the fixed mindset—creates an urgency to prove yourself over and over. If you have only a certain amount of intelligence, a certain personality, and a certain moral character—well, then you’d better prove that you have a healthy dose of them. It simply wouldn’t do to look or feel deficient in these most basic characteristics

To give you a better sense of how the two mindsets work, imagine—as vividly as you can—that you are a young adult having a really bad day:
One day, you go to a class that is really important to you and that you like a lot. The professor returns the midterm papers to the class. You got a C+. You’re very disappointed. That evening on the way back to your home, you find that you’ve gotten a parking ticket. Being really frustrated, you call your best friend to share your experience but are sort of brushed off.
What would you think? What would you feel? What would you do?

When I asked people with the fixed mindset, this is what they said: “I’d feel like a reject.” “I’m a total failure.” “I’m an idiot.” “I’m a loser.” “I’d feel worthless and dumb—everyone’s better than me.” “I’m slime.” In other words, they’d see what happened as a direct measure of their competence and worth.
