No whining. No complaining. No excuses. - Angela Duckworth

...grit grows as we figure out our life philosophy, learn to dust ourselves off after rejection and disappointment, and learn to tell the difference between low-level goals that should be abandoned quickly and higher-level goals that demand more tenacity. The maturation story is that we develop the capacity for long-term passion and perseverance as we get older.

The scientific research is very clear that experiencing trauma without control can be debilitating. But I also worry about people who cruise through life, friction-free, for a long, long time before encountering their first real failure. They have so little practice falling and getting up again. They have so many reasons to stick with a fixed mindset. I see a lot of invisibly vulnerable high-achievers stumble in young adulthood and struggle to get up again. I call them the "fragile perfects." Sometimes I meet fragile perfects in my office after a midterm or a final. Very quickly, it becomes clear that these bright and wonderful people know how to succeed but not how to fail.

As soon as possible, experts hungrily seek feedback on how they did. Necessarily, much of that feedback is negative. This means that experts are more interested in what they did wrong — so they can fix it — than what they did right. The active processing of this feedback is as essential as its immediacy.
