Of course, spending time with family is always good. I love the outdoors, so if I get a chance to go out and hike or bike around, that's always great. If I don't have time to leave, just listening to some music that I love reenergizes me and gives me that break I need to go back to whatever it is I'm doing.

I always loved science and math growing up. I was born in Iran; I grew up there and then came to the United States when I was about 16 years old. And I thought that this was my opportunity to get involved with something really cool and great.

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.

One of the things I do when I'm very stressed out and I can't get out and I need to do something, I just close my eyes and try to remember what it was like to be in space and to float around. And that sort of brings back all of those good sensations and good memories, and it helps me to get through the day.

You have to find things that are accessible and doable in your busy life and try to fit some time in your schedule to just have time to yourself and be able to recoup and refocus.

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.

Of course, spending time with family is always good. I love the outdoors, so if I get a chance to go out and hike or bike around, that's always great. If I don't have time to leave, just listening to some music that I love reenergizes me and gives me that break I need to go back to whatever it is I'm doing.
