I stopped and thought about my “contribution” to the logistics problem, and realized that a man like the guy who orders the stuff for Christmas at Macy’s would be better able to figure out how to handle problems like that than I. So I concluded: a) if I had made an important contribution, it was sheer luck; b) anybody else could have done as well, but most people could have done better, and c) this flattery should wake me up to the fact that I am not capable of contributing much.
