It's not so easy to find out later About the necessary knowledge for survival You think you know enough to get you through life But find out too late of chances passed by An early start is not so important But timing is most essential Opportunity gone, is gone forever You never know how much it could have been And once gone, gone forever You will find out to your cost A better use can be made of your time Don't think that life is easy You may never get a lucky break They'll put you down, cold and unknown A total failure from womb to grave > B-side of 'One Step Beyond' (1979)
