I know a lot of CEOs who are looking for three- to four-year varsity athletes - not necessarily because these people are going to be doing pushups or spiking volleyballs in the workplace, but because they're looking for that continuity, that person who was gritty about something.

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.

Gritty people train at the edge of their comfort zone. They zero in on one narrow aspect of their performance and set a stretch goal to improve it.

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.

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.

If the quality and quantity of continuous effort toward goals matters as much as I think it does, we may actually get more productive, not less, as we get older - even if we can't pull all-nighters like we used to.

I do think that whatever ambition I may have had natively was amplified by my father's clear valuing of it. I knew that was what my dad really cared about.

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.

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.

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