You can be a couple in London who happen to take pictures of their breakfasts every day - it's called @symmetrybreakfast - and you can gain hundreds of thousands of followers overnight because people are genuinely interested in your unique angle on the world.

The world runs on luck.

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."

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.

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.

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.

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.
