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

Every startup should address a real and demonstrated need in the world. If you build a solution to a problem lots of people have, it's so easy to sell your product to the world.

I really value passion for the product above experience.

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.

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.

In the past, people have looked at photos as a record of memory. The focus has been on the past tense. With Instagram, the focus is on the present tense.

The number of people who have either gotten married or had kids or started dating or just made great friends over Instagram is countless. I think we're the only platform that continues to be successful in bringing people together in real life for these real relationships.
