I co-founded Duolingo with the mission of bringing free language education to the world.

It's hard to think of a time when I'm not working, but when that is the case, I like to travel and eat good food.

I am always able to keep a laser focus on one thing at a time without getting distracted. It helps that I try to break everything I do into small, achievable tasks.

Before the Internet, coordinating more than 100,000 people, let alone paying them, was essentially impossible. But now with the Internet, I've just shown you a project where we've gotten 750 million people to help us digitize human knowledge.

I watch a lot of TV. That's how I spend most of my time outside of work. If I had more time, I would fill it 100 percent with watching TV.

In 2011, after spending a couple of years working at Google, I decided that I wanted to dedicate myself to helping to transform education. I was particularly inspired by my upbringing in Guatemala, a poor country where high-quality educational opportunities are limited to those who have money.

I finished reading High Output Management by Andrew Grove, which had such valuable insights for leaders that I've been forcing managers at Duolingo to read the book.
