We observe that as lack of motivation. But behind it is a fixed mindset, whereas people with a growth mindset understand that set backs are part of growth. So when they hit one, they find a way around it. Like Josh Waitzkin did when he lost in chess or in martial arts. Research clearly shows these effects of mindset. In one study Dr. Dweck did with Dr. Claudia Mueller, they had children do a set of puzzles, and then they praised the kids. To some of the kids, they said, "Wow, that's a really good score, you must be smart at this."
