My research started out looking at how people cope with failure and setbacks, especially students who were asked to solve challenging problems. Some students acted as though a failure was a catastrophe, while others actually relished the challenge. I was particularly interested in the latter group. I vowed that I’d figure out what their secret was and try to bottle it. It comes down to whether you focus on growing your abilities, as opposed to proving and validating them all the time. When you’re in what I call a fixed mindset, your goal in life is to prove you’re a smart, competent, worthwhile person and avoid doing things that could undermine that image of yourself. In the growth mindset, you believe these abilities and talents can always be developed, so you’re not on the spot every second to prove yourself, and you can focus on developing those abilities through taking on challenges and seeing them through. You can be more resilient from setbacks because they don’t define who you are. In other words, the fixed mindset is the idea that you have a fixed amount of intelligence, ability, or talent, and the growth mindset is the idea that you can always develop these abilities and talents. Of course, people differ in their abilities, but the underlying premise that separates people is the degree to which they believe they can develop their talents and capacities further.
