I recently saw the Martin Scorcesse Rolling Stones documentary "Shine a Light". It's a fairly long concert film of songs that everyone has pretty much heard many, many times. By a band that hasn't done anything that new or original in some time. But...and it's a large but... I was really struck and impressed by how fully these guys sincerely seem to enjoy doing what they do. 40 years later! With energy and honest enthusiasm that you can't fake. Perhaps if you do the same thing for long enough you come through at the other end with a whole new perception and appreciation of it? It's worth seeing for this alone.
