Kids need playgrounds dangerous enough to remain challenging. People, including children (who are people too, after all) don’t seek to minimize risk. They seek to optimize it. They drive and walk and love and play so that they achieve what they desire, but they push themselves a bit at the same time, too, so they continue to develop. Thus, if things are made too safe, people (including children) start to figure out ways to make them dangerous again. 165 [Nietzsche, F.W. & Kaufmann, W.A. (1982). The portable Nietzsche. NewYork: Penguin Classics, pp. 211-212.] 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. Overprotected, we will fail when something dangerous, unexpected and full of opportunity suddenly makes its appearance, as it inevitably will.
