My girlfriend's a lot more outdoorsy than myself (I'm like a mole, lol), but we make it work. She gets me out of my comfort zone and actually gets me off my lazy ass to exercise. The big thing we have in common, hobby wise, is food - trying new restaurants and cuisines, cooking together, etc. I think it's good to be open to each other's interests, but at the end of the day, shared values are MUCH more important.
