A smartphone is great for when one person is documenting another thing or another person doing something.

Before GoPro, if you wanted to have any footage of yourself doing anything, whether it's video or photo, you not only needed a camera, you needed another human being. And if you wanted the footage to be good, you needed that other human being to have skill with the camera.

You know what the best thing about morning ski trips are? McDonald's!

I can sell anything that I totally believe in, but I'm a horrible salesman of something I don't believe in.

You don't have to raise millions of dollars to be successful, you just have to work on something you are passionate about.
