Marchand--Hail and Farewell, My Friends . . .

We are all at risk of staying too long. Whether as a guest or in a business meeting or even, I suppose, as a columnist. Knowing when it's time to leave may be no less important for columnists than it is for boxers and ballplayers. For me, that time has come.

I haven't lost a step, and I'm still at the top of my game. But nothing erodes desire and competence faster than the loss of motivation.
