"Time，"says the proverb，"is money"．This means that every moment well-spent may put some money into our pockets．
If our time （25） ______ （employ） usefully，it will either turn out some useful and important piece of work which will fetch its price in the market，or it will add to our experience and increase our capacities so as to enable us to earn money when the proper opportunity comes．Let those，（26） ______ think nothing of wasting time，remember this．
Our life is nothing more than our time．To kill time is therefore a form of suicide．We are shocked （27） ______ we think of death，and we spare no pains，no trouble，and no expense to preserve life．
But we often care nothing about the loss of an hour or of a day，（28） ______ （forget） that our life is the sum total of the days and of the hours we live．Our life is a brief period measuring some seventy or eighty years in all．So a day or an hour（29） ______ （waste） is therefore so much life lost．
But nearly one third of this has to be spent in sleep； some years have to be spent over our meals； some in watching over the sick-beds of our （30） ______ （near） relatives； some in making journeys on land and voyages by sea．
Now if all these years were to be decreased from the term over which our life extends，we shall find about twenty or thirty years at our disposal （处置） for active work．（31） ______ remembers this can never willingly waste a single moment of his life．
The precious hours of childhood and youth，if properly used，（32） ______ （supply） us with incalculable advantages．If we allow these morning hours of life to slip away，we shall never be able to make up for the loss．
