I was very much into science when I was young - I wanted to be a marine biologist, then I wanted to be a doctor, and then something else, I was always changing.
Whenever you deal with science fiction you are setting up a world of rules. I think you work hard to establish the rules. And you also have to work even harder to maintain those rules, and within that find excitement and unpredictability and all that stuff.
I'll tell you what's helped me my entire life. I look at baseball as a game. It's something where people can go out, enjoy and have fun. Nothing more.
