“A vivid - if somewhat melodramatic - firsthand description of what deliberate practice can feel like comes from dancer Martha Graham: 'Dancing appears glamorous, easy, delightful. But the path to the paradise of that achievement is not easier than any other. There is fatigue so great that the body cries even in its sleep. There are times of complete frustration. There are daily small deaths.”

“We have found a direct correlation between grit and positive emotions, but the fact that I have no evidence that grit is bad for you doesn't mean it's not. It's always a possibility that in the future researchers will discover a downside to grit.”

“Negative feelings are typical of learning, and you shouldn't feel like you're stupid when you're frustrated doing something. You might say to yourself, 'I can't do this,' but you should say, 'That's great.' That means you really have the potential to learn something there.”

“Many things matter other than our measured intelligence, so let's get to work on them.”

“I think the very idea of character, of developing not just grit, but empathy and curiosity, emotional intelligence - you know, the things that I want my own daughters to develop - the idea that we're going to get there through rewards and punishments seems completely at odds with the idea of character itself.”

“Being gritty doesn't mean not showing pain or pretending everything is O.K. In fact, when you look at healthy and successful and giving people, they are extraordinarily meta-cognitive. They're able to say things like, 'Dude, I totally lost my temper this morning.' That ability to reflect on yourself is signature to grit.”

“When people think of the word 'drive,' they often think you have it or you don't, and that's where we're wrong. Drive is something that can be encouraged by a wonderful teacher, by a terrific classroom environment, by an awesome soccer team that you are on, and it can be squashed as well.”

“I was a good novice teacher, but I did the things that were obvious. I stayed for lunch for extra tutoring, gave kids my cell phone, and was available. In my first year of teaching, I ended up doubling the math time that a conventional school would have. But I don't think any of these things were path-breaking or unusual.”

“I worked hard when I was a consultant. I worked hard when I was in graduate school looking at neuroscience. I worked hard as a teacher. But those are completely different career paths. And the lack of direction is why I didn't get far enough in any of those things.”

“My dad was not super-intentional in his parenting. He was very self-absorbed. I won't say mean or selfish per se, but very self-absorbed. I think he was just thinking out loud.”

“The parenting style that is good for grit is also the parenting style good for most other things: Be really, really demanding, and be very, very supportive.”
