When it comes to success, it’s easy to think that people blessed with brains are inevitably going to leave the rest of us in the dust. But research from Stanford University will change your mind (and your attitude). Psychologist Dweck has spent her entire career studying attitude and performance, and her latest study shows that your attitude is a better predictor of your success than your IQ. Dweck found that core attitudes fall into two categories: a fixed mindset or a growth mindset. With a fixed mindset, you believe you are who you are and you cannot change. This creates problems when you’re challenged because anything that appears to be more than you can handle is bound to make you feel overwhelmed. People with a growth mindset believe that they can improve with effort. They outperform those with a fixed mindset, even when they have a lower IQ, because they embrace challenges, treating them as opportunities to learn something new.
