I don't think it is important for two people to have to share the same interests, I think it is personality that matters far more than interests for a relationship to work.
for my personality, I would describe myself as helpful, nice but quite a bit shy. Good listener, very honest, always willing to help people.
I haven't done too much traveling but would love to see the world outside the U.S. some day
I think I am a very down to earth rational person, I would be perfectly happy to eventually settle down with the house, kids, a dog and such.
