Once you become aware of these concepts ["fixed" vs "growth" mindset], you start to spot the fixed mindset everywhere. Look at the way we praise our children: "You're so smart!" "You are so good at basketball." That's fuel for the fixed mindset. A growth mindset compliment praises effort rather than natural skill: "I'm proud of how hard you worked on that project!" "I could tell you listened to your coach's comments--you really had your elbow under those jump shots today."
