“I now have Grit Scale scores from thousands of American adults. My data provide a snapshot of grit across adulthood.”

Psychologists call this the maturity principle. My own life experience fits this principle to a T.

I believe kids should choose what they want to do, because it’s their life, but they have to choose something, and they can’t quit in the middle unless there’s a really good reason.

During all my undergrad years and in high school, I was involved in tutoring and public service. At Harvard, I spent over 35 hours a week doing service. I was a Big Sister, I worked for the homeless, the elderly; it was the epicenter of my focus.

There’s this really awesome theory of human motivation – that human beings all want three things. One is to be competent, one is to belong, and one is be free, as in to have choice: to not be told what to do but to choose what to do.

When people think of the word ‘drive,’ they often think you have it or you don’t, and that’s where we’re wrong.

I do feel it’s hard to be modest and humble and egoless when people are telling you you are so great and wanting to give you prizes and energy. I’m trying hard not to be an awful, narcissistic human being.

One thing that’s true of gritty people is they love what they do, and they keep loving what they do. So they’re not just in love for a day or a week.

Most teachers, when surveyed, say that it is part of their job to help students develop things like grit. This is especially true at the elementary and middle school levels. They feel it’s part of their vocation to teach other things that are not formally academic content.

I will say that if my wildest dreams come true, I will, like, wake up one day, and I will be Carol Dweck, right? Because she is like everything I want to be.

I define talent as the rate at which you get better at something when you try. To be very talented means you get better faster and more easily than other people or other things that you try.

Grit may carry risk because it’s about putting all your eggs in one basket, to some extent.

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.

Maybe. But the reality is that our early interests are fragile, vaguely defined, and in need of energetic, years-long cultivation and refinement.

At various points, in big ways and small, we get knocked down. If we stay down, grit loses. If we get up, grit prevails.

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

Why do some people try, try again, and why do some people not? That’s what I’m after.

Accepting where you are means scaling a mountain of love and patience.

We are only what we are; not what we would be; nor every thing we hope for. We are but a step in a scale, that reaches further above us than below.

Measure not by the scale of perfection the meager product of reality.

It seems like I always had to work harder than other people. Those nights when everybody else is asleep, and you sit in your room trying to play scales.

I don’t own a scale, and Tao banned the word ‘fat’ from our house. If we eat too much, we say, ‘I feel clogged up.’

I think I’m much more afraid of making a mistake in raising my daughters than I would be with any work that I do, as an actor. It’s a much higher scale of fear, raising kids.

Perhaps there could be no joy on this planet without an equal weight of pain to balance it out on some unknown scale.

There’s this idea that because I’m a heavyweight, I’m not supposed to be in condition, that I should take advantage of the fact that I can eat. But I train and eat well, and it shows when I step on the scales.
