No, honestly Jim. A pro who says he makes a good living by reluctantly selling his cds is a saint to me!
I too do very well, like people, and owe my good life to my audience whom I respect greatly as they have to work hard to find people like us in the modern noisy world of hype. But I feel worth my corn and worth my coin.
I find confidence is a big factor in a pro's life and selling myself for as much as the marketplace will let me gives me the confidence to believe in myself. With all and sundry making cds, giving them away, being flattered by one or two downloads, etc I can only feel my work is valuable to people if they are willing to purchase it. I think this is true of most creative people who have to pay the same bills as someone with a guaranteed income.
