When I was 27 years old, I left a very demanding job in management consulting for a job that was even more demanding: teaching. I went to teach seventh graders math in the New York City public schools.


Grittier students are more likely to earn their diplomas; grittier teachers are more effective in the classroom. Grittier soldiers are more likely to complete their training, and grittier salespeople are more likely to keep their jobs. The more challenging the domain, the more grit seems to matter.

You cannot will yourself to be interested in something you're not interested in. But you can actively discover and deepen your interest.

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.

Grit, in a word, is stamina. But it's not just stamina in your effort. It's also stamina in your direction, stamina in your interests. If you are working on different things but all of them very hard, you're not really going to get anywhere. You'll never become an expert.

As our knees and hips and eyesight deteriorate, we become more dependable, less impulsive, kinder, and less moody. Psychologists call this the maturity principle. My own life experience fits this principle to a T.

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.

The focus on just thinking about standardized test scores as being synonymous with achievement for teenagers is ridiculous, right? There are so many things that kids care about, where they excel, where they try hard, where they learn important life lessons, that are not picked up by test scores.

Boredom is a very self-conscious emotion by definition. Interest is not. So you can actually be completely absorbed in something and, at certain points in your development, not even realize that you're into it.

To me, the most shocking thing about grit is how little we know, how little science knows, about building it. Every day, parents and teachers ask me, 'How do I build grit in kids? What do I do to teach kids a solid work ethic? How do I keep them motivated for the long run?' The honest answer is, I don't know.

I'm not a policy oriented person. I'm constrained to what I study. But educational policy has not yet taken adequate note of the whole child. Kids are not just their IQ or standardized test scores. It matters whether or not they show up, how hard they work.


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.
