"I have a first principle for becoming the person you want to be. Follow it and it will dramatically 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 in any situation where 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? It's a question that pops into my head so often each day that I've turned the first five words into an acronym, AIWATT (it rhymes with "say what"). Like the physician's principle, 'First, do no harm,' it doesn't require you to do anything, merely avoid doing something foolish."
