When I think of the artists I admire and seek out musically. It's because I'm curious about where they're going to go the next time they have a chance to put a record out. It's not about where I find them on the radio dial, or how many records they're selling.
When I was playing I felt tired all the time. My recovery period was a lot longer than the other players. They'd be ok after an hour - I'd have to stay in bed till the next session.
