Cover art for Time lyrics by Ozzy Osbourne

Ozzy speaks about living in the moment, or living for now. Nobody can just sit around and day dream their whole lives, for they have to take charge for themselves. Live it up as much as possible because when shit hits the fan in your life you'll be missing those good times. I'm not quite sure what the whole time bomb metaphor is about. I think it's something about impending death that you face in the future. Lyrics are kinda self explanatory. This is my opinion.
