Focusing on one thing and doing it really, really well can get you very far.

I grew up as a photo nut. Every Christmas I would get a new camera. It's a huge part of my life.

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.

I’m always in awe of people who are artists in their fields – people who understand that simply by taking ideas and translating them into reality, they’ve created value in the world.

People interact with their phones very differently than they do with their PCs and I think that when you design from the ground up with mobile in mind, you create a very different product than going the other way.

I promise you, a lot of it is luck. But you make your own luck by working really hard and trying lots and lots of things.

You need to fail in order to find the right solution.
