I have a GoPro in the trunk of my streetcar.

Your passions are a bit like your fingerprints: Everybody has them; everybody's are different. One's passions may just be a guidebook to one's life.

It's very difficult to get any footage of yourself doing what you love unless you have a friend who's a photographer or videographer and wants to document you. That was really the idea and the goal from the beginning: to help people get a good photo, and then it was to help people get a good video.

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.

When I got out of college, I gave myself till I was 30 to invent a product. If I couldn't do it by then, I would just get a real job. And that fear - the fear of a real job - motivated me to be an entrepreneur.

When I have a difficult decision to make, I imagine myself as a 90-year-old guy looking back on his life. I imagine what I'll think about myself at that point in time, and it always makes it really easy to go for it. You're only going to regret that you wimped out.
