Being an entrepreneur does require a lot of sacrifice of your personal time and personal hobbies and things that you enjoy. At least for the period of high growth that you experience at the beginning of a company's life cycle, you have to be ready to make a lot of time sacrifices and personal sacrifice.

One of the things that really gets me excited and makes me start up companies is the fact that you can basically build something new, try to introduce a change in a way that people are used to doing certain activities, and basically create something out of scratch that doesn't exist and would revolutionize whatever it is that you are trying to do with it. So that's part of the reason I love being able to be a technologist.

It is a very naive view to think that the resources and conditions on earth would last forever. Our race has to take necessary steps to be able to develop the technology necessary to live on other planets and moons and to reach to farther corners of the galaxy.

I wasn't frightened going to outer space. I'd been living this in my head for many, many years, so I sort of had played all of these scenarios of flying into space and seeing earth. I think I was very prepared for it. It was almost a completely joyful, very happy, very exciting experience, and I didn't have time or any desire to think about what things could go wrong.

Being an entrepreneur is really exciting for me. Whether it's creating something or just building a company and giving others the opportunity to build a career, I think it's exciting to be at the helm of these types of activities.

One of the most memorable moments was when I first saw earth because I had seen many pictures, many videos of earth from space, and being able to see that with my own eyes had a completely different effect, and sort of almost sensing life emanating from our planet in the dark background of the space, it was a really memorable experience.

One of the coolest things with the Internet is that it is used by the entire population - as part of education and just on a daily basis for communication. I think that has been one of the coolest technologies that has been developed.
