This is the first single from Album 21. There's also a video for it, but that is a tale for another time.  The tune has to do with artistic regeneration amid a hostile world, but doesn't delve into all that "Life is...(whatever you say it is)" kind of metaphoric quicksand.  All I'm saying is the things are not easy or certain, and at the end of this time, you should have learned something, either about yourself or about your craft.  If you haven't what was the point of wandering around in the first place?
