I think the thing that I've learned is that really great people, they actually want to work on hard problems.

As a kid, I always idolized entrepreneurs. I thought they were cool people in the way that I thought basketball players were cool people. It's cool that some people get paid to dunk basketballs, but I'm not one of those people.

I thought Google was the coolest place. People there were so smart and they were all doing these really interesting things. I just felt really lucky to be a part of it even in a small way.

Don't take too much advice.

I look around my neighborhood, and I see people hailing a cab or ordering their food and then paying for it all with their phone. I've read about that stuff for a really long time, and now it's starting to become commonplace.

I always read about these stories of entrepreneurs - it’s like they’re in the desert with no water, and they’re the ones that survive. But I’ve been really fortunate to have people on my team who are optimistic about the future and who know that if you work through hard times that there’s usually something good at the end.
