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

With Instagram, the focus is on the present tense.

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."

A lot of the earliest Instagram celebrities took really beautiful photos. But you're starting to see a change where it's not about beauty; it's about the story that you tell.

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

Above all else, products spread when they're useful and they're usable

I think Instagram at its best is where you feel like you're getting the most authentic version of the person on the other side of the camera.
