People have presences, both online and in real life. You can choose to show everything, meaning all sides of you, or you can choose to be selective.

I think not focusing on money makes you sane, because in the long run it can probably drive you crazy.

If you've got an idea, start today. There's no better time than now to get going.

Everyone gets lucky for some amount in their life. And the question is, are you alert enough to know you're being lucky or you're becoming lucky?

Instagram is a media company. I think we're about visual media. I explain ourselves as a disruptive entertainment platform that enables communication through visual media. I don't think it's just photos. There's a reason we don't allow you to upload photos on the Web as albums. It's not about taking all these photos off your DSLR putting them into an album and sharing them with your family. It's not about that. It's about what are you up to right now out in the real world, how can you share that with everyone.

The number of people who have either gotten married or had kids or started dating or just made great friends over Instagram is countless. I think we're the only platform that continues to be successful in bringing people together in real life for these real relationships.
