Compromise... Friend or foe?

The art of compromise... To find a happy medium between two opinionated people. Is it fine to compromise in every area in life? I mean if I want Chinese food but can't make it to pfchangs I go to the scarry place... Or if I really want sonic I go to the gas station and mix something unique. When I bought a car, I wanted an Altima and settled for a civic. Is it ok to compromise everywhere? What about in a man? How far is too far to compromise? As a Christian, is salvation really the only uncompromisable quality? As I get older how far is it ok to compromise? I have seen many friends compromise in this area and some are super happy while others seem entirely miserable. Where is the boundary? At 33, is it time to compromise everything and settle just for a Christian? Or do I still have time to wait for someone who meets some of those what seem like unattainable qualities of the imaginary perfect guy? Where are the boundaries?
