When untrammeled—and encouraged—we prefer to live on the edge. There, we can still be both confident in our experience and confronting the chaos that helps us develop. We’re hard-wired, for that reason, to enjoy risk (some of us more than others). We feel invigorated and excited when we work to optimize our future performance, while playing in the present. Otherwise we lumber around, sloth-like, unconscious, unformed and careless.
