In a few hundred years, when the history of our time will be written from a long-term perspective, it is likely that the most important event historians will see is not technology, not the Internet, not e-commerce. It is an unprecedented change in the human condition. For the first time–literally–substantial and rapidly growing numbers of people have choices. For the first time, they will have to manage themselves. And society is totally unprepared for it.
– Peter Drucker, Managing Knowledge Means Managing Oneself, quoted by Marshall Goldsmith in The Earned Life, p. 54
