It does pain me to post this, but it's a good think piece:
Last Friday night, Bob Dylan chugged through "Highway 61 Revisited" at the Borgata, an Atlantic City, N.J., casino. His always-raspy voice, now deteriorated to a laryngitic croak, echoed through the no-frills ballroom. Security guards wandered the seated audience, enforcing his no-cameras policy. Behind some empty rows in the rear, a handful of dancers shimmied mildly. A trickle of people peeled off for the exit, descending an escalator into the ringing rows of slot machines. One of the walkouts, 50-year-old Warner Christy, said he wouldn't be paying to see the singer again: "I've been scared straight."
For people of influence in any walk of life, from corporate leaders to sports stars, the question of when to leave the stage is a crucial one. Do you go out at the top of your game, giving up any shot at further glory? Or do you dig in until the end, at the risk of tarnishing a distinguished career?
