How many common interests do you and your significant other have in common?

I don't know exactly what I want in a relationship. My personal interests are Paleontology, Zoology, Astronomy, Geography, Earth Science, Marine Biology, History, Music, Video Games, and Trains. My favorite music is Classic Rock (I do like a few artists that aren't classic rock). I'm not athletic or anything, I can't throw a ball at all. I don't hate sports though. I want a girl that has things in common with me. I want her to like Classic Rock but for there to be a few artists that she likes that I don't care for. I want a girl that's really into video games and is musically talented. I also wouldn't mind if she was interested in Astronomy, enjoyed Anime, and played any sports such as tennis. What I want is for a girl to have a few commons interests with me but have as many differences so the relationship won't get boring. What do you and your significant other have in common?
