Principles are ways of successfully dealing with reality to get what you want out of life.

I have seen people who agree on the major issues waste hours arguing over details. It's more important to do big things well than to do the small things perfectly. But when people disagree on the importance of debating something, it probably should be debated. Operating otherwise would essentially give someone (typically the boss) a de facto veto.
