Why did you decide to get a degree in literature after all you had accomplished in your life?

I wanted to get a degree in literature to try to have a better experience in space -- to try to catch what the meaning of space was. To be able to get it, and to talk about it and write about it in poetic terms. To bring space back to people. Because I've had the privilege of being there, as part of my responsibility, not only to get the mission done, but also to try to bring that experience to other people. To try to put spaceflight in some form of context and perspective. To try to discover what is the meaning of spaceflight. To examine spaceflight in terms of the classical authors and the classical literary works.
