Some people are not able to enjoy the present or prepare for tomorrow because they are still living in the past. Dr. Warren W. Wiersbe has put it like this: "Do not say, "Why were the former days better than these?' You do not move ahead by constantly looking in a rear view mirror. The past is a rudder to guide you, not an anchor to drag you down. We must learn from the past but not live in the past." Or as Thomas Holdcroft once put it, "The past is a guide post, not a hitching post."
