People have presences, both online and in real life. You can choose to show everything, meaning all sides of you, or you can choose to be selective.

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

Having a company that's successful is a wonderful platform to do new things. You don't have to raise money for it; you can take profits from the company and pump them into new business.

You can be a couple in London who happen to take pictures of their breakfasts every day - it's called @symmetrybreakfast - and you can gain hundreds of thousands of followers overnight because people are genuinely interested in your unique angle on the world.

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.

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.

I have a pretty random life. I run a business and go all over the world doing things for that business, things that are fairly orthogonal. But my job is to run my company, not to be the best Instagrammer. I'll let other people be awesome at it.
