 I thought of being an astronaut kind of like being a professional football player. Like little kids might dream of doing that, but come on, that's not really reality. And I put that in the same ballpark. I thought, that would be really awesome, but superheroes would do that. And I'm not a superhero. And we tell the candidates that come and they want to be astronauts and they always ask us and they say, should I go to this university? Should I major in this or that? Should I get this job? And we say you have to do what you're passionate about because otherwise you're never going to have enough energy to do all the hard work that it takes if you don't actually enjoy doing it.
