As an astronaut, you have a very defined set of tasks to do. Those tasks may require you to work 60, 70 or 80 hours a week.

Science provides an understanding of a universal experience, and arts provides a universal understanding of a personal experience.

Sciences provide an understanding of a universal experience, Arts are a universal understanding of a personal experience... they are both a part of us and a manifestation of the same thing... the arts and sciences are avatars of human creativity

Never limit yourself because of others' limited imagination; never limit others because of your own limited imagination.

Once I got into space, I was feeling very comfortable in the universe. I felt like I had a right to be anywhere in this universe, that I belonged here as much as any speck of stardust, any comet, any planet.

The difference between science and the arts is not that they are different sides of the same coin… or even different parts of the same continuum, but rather, they are manifestations of the same thing. The arts and sciences are avatars of human creativity.

Never be limited by other people's limited imaginations.
