Michael Lewis写道： Alexander insisted at our farewell dinner that I was making a great move. The best decisions he has made in his life, he said, were completely unexpected, the ones that cut against convention. Then he went even farther. He said that every decision he has forced himself to make because it was unexpected has been a good one. It was refreshing to hear a case for unpredictability in this age of careful career planning. It would be nice if it were true.
