You two are such a mismatch when it comes to what's important to you in life that you may not become friends in the first place. You're just on two completely different pages; you're not even opposed, like an atheist and a priest or a war protester and an Army general; you're more like...a kangaroo and a generator. A mathematician and a fisherman.
You're just apples and oranges, and neither of you will be able to understand the other's passion for their ideals and vocation. There's not much to say about this kind of mismatch; it just probably won't happen. You need a friend who's on the same page as you.
