Unpredictability is part of life. Some surprises are wonderful; others are devastating.  Not thinking about the devastating variety for now, anticipating unpredictability in other areas of our lives, and this applies to healthy organizations as well, is the mature approach to living.  In ways it can be a gift.  Avoid the dreaded routine/rut/rigor-mortis syndrome!  (Episode art:  "Under The Great Wave off Kanagawa," Hokusai Katsushika, public domain)
