With a fixed mindset, you're so worried about how smart or talented you are, you don't take on challenges. You don't try new things.

When there's a setback, someone with a fixed mindset will start thinking, 'Maybe I don't have what it takes?' They may get defensive and give up. A hallmark of a successful person is that they persist in the face of obstacle, and often, these obstacles are blessings in disguise.

The hallmark of successful people is that they are always stretching themselves to learn new things.
