The companies that I really admire the most are the ones that have a deep visceral understanding of why people use their service, and they figure out ways of making money that are completely consistent with how people are feeling and what they are doing at the time.

I always describe Facebook and Twitter to some extent as 'them time': it's time about the world and what's outside of you. Pinterest, for a lot of users, is 'me time.' What do I want my future to be? Who am I? What are the things I want to do?

I hope Pinterest is my last job.

When you open up Pinterest, you should feel like you've walked into a building full of stuff that only you are interested in. Everything should feel handpicked for you.

I am a very big fan of Brian Eno, of his work as an artist and making his music, and as a producer. In some ways, I have looked to his career as a model for my own.

It is inevitable that popularity will fade. That's why I must always be prepared. I don't want a meteoric rise in popularity. I want to be an actor who can quickly get back on my feet after a fall. If I want to have a long-term career in acting, I must be careful about the choices I make.

I look at careers like Ben Stiller and think that's a great career to have where you're doing movies that you write and direct, and also act in films, although he's primarily an actor.

I've never been interested enough to have a career trajectory. I've never had any ambition or thought of what I should be doing or had any idea of what I'd like to do. Never. And still don't. And if something comes along, I say 'Fine.'
