Most disputes don’t really matter in your life. Work on the ones that do matter — the ones involving loved ones, important colleagues, valued others — and walk away from or quickly resolve the rest.
For the ones that don’t really matter (will you remember and care about them tomorrow? in a week? in six months?), keep it simple, stop your histrionics, find something simple like rock, paper, scissors, and get on with living life. Simple, unimportant disputes deserve simple, easy methods for getting it done and moving on.
