To sell is above all to master the art and science of listening.
Business isn't some disembodied bloodless enterprise. Profit is fine - a sign that the customer honors the value of what we do. But "enterprise" ( a lovely word ) is about heart. About beauty. It's about art. About people throwing themselves on the line. It's about passion and the selfless pursuit of an ideal.
The 10 or 12 artists I have known really well all my life are at least as competitive as professional athletes. They may express it in slightly different terms, but you look at the Jackson Pollocks et al., and they are as interested in wall space in the galleries as Joe Montana is in the percentage of completed passes. So the notion that symphonic conducting, or stage play, or pure art, is not a competitive business is real bullshit.
