What if there were a single question you could ask yourself that would guide just
about every decision you need to make in your life? A question that would bring clarity
and fresh insight for every choice you have to make? A question that would pierce the
fog of your self-deception and erase all those shades of gray that cloud your reasoning? A question that would sidestep waste of effort and prevent useless regret,
fool-proofing every aspect of your life?
