The success my children have had has helped me immensely. I've showed them a certain respect for this career.
And then I met Jerry and he's such a creative fiction writer, and I don't know if there's ever been a team put together the way we are - where one person does the theological way out and suggestions, and the other person goes into the cave and does the fiction writing.
And then finally, I'm the commander, so I am fundamentally responsible for the lives of the other people on board and the health and longevity of the space station. I need to bring six people back happy, healthy and feeling like they've had the best six months of their life.
