Random tinkering is the path to success. And fortunately, we are increasingly learning to practice it without knowing it–thanks to overconfident entrepreneurs, naive investors, greedy investment bankers, confused scientists and aggressive venture capitalists brought together by the free-market system.

We need more tinkering: Uninhibited, aggressive, proud tinkering. We need to make our own luck. We can be scared and worried about the future, or we can look at it as a collection of happy surprises that lie outside the path of our imagination.
