“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.”

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.

Longitudinal studies following thousands of people across time have shown that most people only begin to gravitate toward certain vocational interests, and away from others, around middle school.

There haven’t been genetic studies on grit, but we often think that challenge is inherited but grit is learned. That’s not what science says. Science says grit comes from both nature and nurture.

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 stayed for lunch for extra tutoring, gave kids my cell phone, and was available. In my first year of teaching,

As our knees and hips and eyesight deteriorate, we become more dependable, less impulsive, kinder, and less moody.

I didn’t tell my kids, ‘You have to play viola, and you have to play piano.’ They chose these things on their own, and I don’t think we have to give kids every choice, but we do have to give them some choice because that autonomy is crucial for fostering passion.

Many, many individuals will report starting to form their lifelong interests around adolescence. Why that is, researchers don’t fully know. But if you can take a trip down memory lane and see what interested you, that’s at least a clue as to where your interest may begin to develop.

It is important to realize that the process of ‘fostering’ a passion takes trial and error. It takes experience; you cannot do it all in your head. And it takes a long time.

I worked hard when I was a consultant. I worked hard when I was in graduate school looking at neuroscience.

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.

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.

So when my daughter told me on the second track meet that she was done with it because she discovered she didn’t like competing, I made her finish the season.

The focus on just thinking about standardized test scores as being synonymous with achievement for teenagers is ridiculous, right?

People who are really gritty – they’re still interested.

Most people who are really, enduringly interested in something eventually find that it’s important, too – and important to other people.

My thoughts are that marriage is between a man and a woman.

The experimental investigation by which Ampere established the law of the mechanical action between electric currents is one of the most brilliant achievements in science. The whole, theory and experiment, seems as if it had leaped, full grown and full armed, from the brain of the ‘Newton of Electricity’.

I had that. I could almost feel the miles between us shrinking, as if we were at two ends of some invisible elastic thread.

The danger always exists that our technology will serve as a buffer between us and nature, a block between us and the deeper dimensions of our own experience.

It is not usually possible in a poem or a story to make the relationship between particular and universal fully explicit. Those who try to do so end up writing parables.

The relationship between commitment and doubt is by no means an antagonistic one. Commitment is healthiest when it is not without doubt but in spite of doubt.

There were several ways of understanding her: there was what she said, and there was what she meant, and there was something between the two, that was neither.

The book is all there, all at once, between its covers. But if you want to read the story and understand it, you must begin with the first page, and go forward, always in order. So the universe would be a very great book, and we would be very small readers.
