How Do You Tell if a Relationship Is Worth Fighting For?

i'm going to group two questions together about relationship advice. Casey mahone asks, how can you tell whether a relationship is worth fighting for? And michel says, what is your advice for dealing with people who are condescending and self important? I don't by grouping these together, mean to imply that casey's relationship is with someone who is condescending andself important. But there are certain commonalities between these two questions. The older i get, the more my philosophy of relationships is just have relationships with good people from the start,. rather than having relationships with not good people and trying to fix them.
