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.

My older brother and I read all the time. My father read, but only things related to religion. One year, he did read a set of stories that was called something like '365 Stories' out loud to us. They followed a family for the year, a page a day. They were about kids with simple problems - like a wheel coming off their bicycle.

We actually have a small family. It's just my father and I and my grandmother, who lives in Tokyo. I cherish my friendships.

I'm very supportive of women getting to a place in life when it's right for them to start a family. It's important for women to take their time to come into their own. I only want to say we might not have as much time as we think we have.

The best thing we can do to save the planet is set a good example for our kids at home.
