If you’re somebody when you’re successful, what are you when you’re unsuccessful? - Carol S. Dweck

As children, we were given a choice between the talented but erratic hare and the plodding but steady tortoise. The lesson was supposed to be that slow and steady wins the race. But, really, did any of us ever want to be the tortoise? No, we just wanted to be a less foolish hare. We wanted to be swift as the wind and a bit more strategic — say, not taking quite so many snoozes before the finish line. After all, everyone knows you have to show up in order to win. The story of the tortoise and the hare, in trying to put forward the power of effort, gave effort a bad name. It reinforced the image that effort is for the plodders and suggested that in rare instances, when talented people dropped the ball, the plodder could sneak through.

The fixed mindset limits achievement. It fills people’s minds with interfering thoughts, it makes effort disagreeable, and it leads to inferior learning strategies. What’s more, it makes other people into judges instead of allies. Whether we’re talking about Darwin or college students, important achievements require a clear focus, all-out effort, and a bottomless trunk full of strategies. Plus allies in learning. This is what the growth mindset gives people, and that’s why it helps their abilities grow and bear fruit.

There are so many ways the fixed mindset creates groupthink. Leaders are seen as gods who never err. A group invests itself with special talents and powers. Leaders, to bolster their ego, suppress dissent. Or workers, seeking validation from leaders, fall into line behind them.
