I would probably run away from anyone who said this to me, but I talk to myself in a really mean way fairly often. So I would say, notice your self-talk. Notice exactly what you say to yourself in your own mind, particularly when you're up against a challenge or you've experienced a failure. So, if you're experiencing more of a fixed mindset, you might think things like, "Ugh, I'm so bad at this," or, "There's no way I can do this," or "Ugh, that just shows what an idiot I am." And that brand of thinking naturally leads to quitting or giving up. So, if I already believe that I'm really bad at something, then it would be the logical thing to go ahead and quit because I've already decided I can't do it. There's a logic to it, but there's a logic to growth mindset too.
