Come to think of it, this is what usually happens not only to our programs but to ourselves. Oh, how often our efforts to remove the needless things from our lives lead us to needless situations. Wishing to remove the needless weight we damage our muscles and tendons and are getting hernias. Wishing to spend the needless money we meet people we do not need to know, do things we do not need to do and waste our time. At the end we learn the hard way that out of all imaginable things time is never needless.
