We should not say that one man's hour is worth another man's hour, but rather that one man during an hour is worth just as much as another man during an hour. Time is everything, man is nothing: he is at the most time's carcass.
One cannot buy, rent or hire more time. The supply of time is totally inelastic. No matter how high the demand, the supply will not go up. There is no price for it. Time is totally perishable and cannot be stored. Yesterday's time is gone forever, and will never come back. Time is always in short supply. There is no substitute for time. Everything requires time. All work takes place in, and uses up time. Yet most people take for granted this unique, irreplaceable and necessary resource.
Since time is the one immaterial object which we cannot influence -- neither speed up nor slow down, add to nor diminish -- it is an imponderably valuable gift. Each of us has a few minutes a day or a few hours a week which we could donate to an old folks home or a children's hospital ward. The elderly whose pillows we plump or whose water pitchers we refill may or may not thank us for our gift, but the gift is upholding the foundation of the universe.
What comes first, the compass or the clock? Before one can truly manage time (the clock), it is important to know where you are going, what your priorities and goals are, in which direction you are headed (the compass). Where you are headed is more important than how fast you are going. Rather than always focusing on what's urgent, learn to focus on what is really important.
When as a child I laughed and wept, time crept. When as a youth I waxed more bold, time strolled. When I became a full-grown man, time RAN. When older still I daily grew, time FLEW. Soon I shall find, in passing on, time gone. O Christ! wilt Thou have saved me then? Amen.
