I actually think some of my best moments in life have been while I was with people from Instagram - whether it's super late nights getting a release out or being able to travel to places I'd never visited and meeting some of the most interesting people I've ever met.

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

Obviously, being the CEO, there are a lot of eyes on what you do and what you post and how you post, and I think one of the challenges of Instagram in general is that, as we get bigger, there are just more voices in the room, more eyes on everyone's accounts.

I love challenging the notion that, in order to be a tech founder, you have to be holed up in a dark room wearing a T-shirt and baggy jeans.

Teens just understand the world in ways I don't think any of us adults do.

What people tell you and how they act is very, very different sometimes.

Great products sell themselves.
