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

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.

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.

I usually make to-do lists with timelines, and pen and paper does the trick for me.

Every time you buy tickets on Ticketmaster, you help to digitize a book.

Because education is such a broad area, I chose to focus on language learning.

I worked on a number of projects that were used by millions of people and that also served as inspiration to what we now call "crowd-sourcing."
