The problem is knowing when what you are about to do will make a difference. I’m not only speaking of the small actions that, cumulatively, over time, or in great numbers, alter the course of events in ways too chaotic or subtle to trace ... if everyone were to consider all the possible consequences of all one’s possible choices, no one would move a millimetre, or even dare to breathe for fear of the ultimate results.
