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

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

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.

What's awesome about social media is you curate your own experience. That leads to the rise of niche celebrities, who are actually just as popular as mass celebrities, but because there's no incentive for traditional media to invest in them as celebrities, they find a home where people can follow them on Instagram.

When people say that college isn't worthwhile and paying all this money isn't worthwhile, I really disagree. I think those experiences and those classes that may not necessarily seem applicable in the moment end up coming back to you time and time again.

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.

The major reason why Instagram works is that you can follow anyone out there and start following their photos immediately.
