Working at a startup to make a lot of money was never a thing, and that's why I decided to just finish up school. That was way more important for me.

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

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

If you've got an idea, start today. There's no better time than now to get going.

Instagram is a media company. I think we're about visual media. I explain ourselves as a disruptive entertainment platform that enables communication through visual media. I don't think it's just photos. There's a reason we don't allow you to upload photos on the Web as albums. It's not about taking all these photos off your DSLR putting them into an album and sharing them with your family. It's not about that. It's about what are you up to right now out in the real world, how can you share that with everyone.

I believe photos is one of the underlying things in every social network that becomes successful.
