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.
I think that devices like Glass are going to do a terrific job of capturing your first-person perspective. And that's what people first think of when they think of GoPro.
I feel like I've done a pretty good job of scaling because I got some great mentors along the way that helped me realize I just have to build a phenomenal team around me that makes my job a lot easier.
