I always look toward teens on Instagram to really understand what's going on. For some reason, when you're a teen, you just understand the world better than anyone else.

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

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

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.

Every one of us is prone to implicit sexual prejudices, including women.

Some falls the means are happier to rise.
