When I asked people to tell me when their fixed-mindset persona usually shows up, here’s what they said: “When I’m under pressure, my fixed-mindset persona appears. He fills my head with noise and keeps me from paying attention to the work I have to do. Then I feel like I can’t accomplish anything. Feelings of anxiety and sadness also attract him. He attempts to weaken me when I’m already feeling down. He makes comments like ‘You don’t have the ability to grasp difficult concepts. You have reached your limit.’ ” (By the way, this was a woman who thought of her fixed-mindset persona as a male.)
