Book excerpt: Time needs your tender loving care because it is a unique, irreplaceable resource. Taking it for granted would be your undoing. Time is not found on supermarkets shelves in case you need an extra supply. There are no vending machines even. There is no place where you can buy or hire extra time. Neither you can pull it out from the last year’s stock. As the Sun sets on the horizon, your day is gone and as the Sun rises in the east, your night is gone. Gone means gone for ever, never to return. There are many things in life which go and come back but time is not one of those.
