Never be limited by other people's limited imaginations. If you adopt their attitudes, then the possibility won't exist because you'll have already shut it out...You can hear other people's wisdom, but you've got to re-evaluate the world for yourself.

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

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.

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.

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.

When I'm asked about the relevance to Black people of what I do, I take that as an affront. It presupposes that Black people have never been involved in exploring the heavens, but this is not so. Ancient African empires - Mali, Songhai, Egypt - had scientists, astronomers. The fact is that space and its resources belong to all of us, not to any one group.

Greatness can be captured in one word: lifestyle. Life is God's gift to you, style is what you make of it.
