I think it really depends on what the differences are. I'm over- emotional, generally pessimistic and highly spiritual. My husband expresses very little, is an optimist and an agnositic (he says atheist but I've seen the spark of curiosity when I'm discussing spirituality with others).
We both love music, our tastes meeting at heavy metal and a lot of it's sub-genres though we are both open to learning what each other likes about music we don't like. We both love a concert and try to get to atleast one concert a year. We both love to read and we have other complementary interests like him enjoying card tricks and me enjoying balloon modelling, so we both enjoy certain types of stores. We both enjoy art.
As you can see I focus on our similarities rather than our differences.
