“I have a first principle for becoming the person you want to be. Follow it and it will shrink your daily volume of stress, conflict, unpleasant debate, and wasted time. It is phrased in the form of a question you should be asking yourself whenever you must choose to either engage or “let it go.” Am I willing, at this time, to make the investment required to make a positive difference on this topic?” (Marshall Goldsmith, Mark Reiter, Triggers)
