I can't think of any huge differences I have with my bf. But in general, you just have to accept differences, and though you can discuss it, don't try to talk them out of it- ie a religious person trying to convert an atheist, etc. Just learn to understand their point of view even if you don't agree with it. You have to respect them - if you start thinking less of them because of a "stupid" opinion they hold, it wont last.
