"A long career in business has impressed upon me the unpredictability of success. As an entrepreneur and investor this lesson is particularly sobering. When I started, I felt that my hard work and a modicum of intelligence would propel me to certain success. Simply put one foot in front of the other. But living in the Silicon Valley casino has changed my view. Success is, after all, relative. There is much written about the short half-life of the joy experienced after receiving a significant windfall if others have received an even greater sum. It seems we can't even gauge our own success without comparison to others. And in Silicon Valley, the relative distribution of success appears largely random. That is not to say that many of the successful icons of innovation aren't impressive; it's to say that in comparison to so many of the also-rans they are virtually indistinguishable. And that realization alone is humbling."
