You need to find people that are drawn to the idea that you build, and they end up taking it and making it even better.

Instagram is a media company. I think we're about visual media.

I always look toward teens on Instagram to really understand what's going on. For some reason, when you're a teen, you just understand the world better than anyone else.

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.

Having a company that's successful is a wonderful platform to do new things. You don't have to raise money for it; you can take profits from the company and pump them into new business.
