A former co-worker and I were both fans of a singer/drummer who said he feels "subconscious guilt" about the amount of money he's paid and feels he "should work all the time for it."
After mentioning this quote to my co-worker, he responded sarcastically, "That's a nice thought."
I probably should have expected that response. My guess is, a lot of listeners, even ardent fans, feel that way often about successful musicians.
