"I try to be the best husband and father I possibly can. And it doesn't mean I get to spend as much time with my family as I'd like, but I do the best I can. Even if you do get to be an astronaut and get to go and do a lot of interesting things, at some point that will come to an end. If in the process you short change your family or compromise your values along the way, when you get through on the other side, it won't really be worth it. At least not to me."
