Even artists and writers fall into ruts.

--Is what you are doing worth doing everyday?
--Does it give you true satisfaction, or is it out of sheer habit or compulsion?
--Is it making you a better person?
--Are you continuing to learn from it, or have you reached your ceiling and must move on to something else?
--Is it merely a mechanism to call attention to yourself and subconsciously ask others for affection?
--Are you profiting materially from what you are doing?
--Are you still what you were ten years ago?
