You need to find people that are drawn to the idea that you build, and they end up taking it and making it even better.

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.

The world runs on luck.

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.

Our goal is to not just be a photo-sharing app, but to be the way you share your life when you're on the go.

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

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.
