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

I was never as focused in math, science, computer science, etcetera, as the people who were best at it. I wanted to create amazing screensavers that did beautiful visualizations of music. It's like, "Oh, I have to learn computer science to do that."

People always told me photos have been done. My feeling was, these people are wrong.

I have a pretty random life. I run a business and go all over the world doing things for that business, things that are fairly orthogonal. But my job is to run my company, not to be the best Instagrammer. I'll let other people be awesome at it.

With Instagram, the focus is on the present tense.

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.

The world runs on luck.
