     Hidden in our subconsciousness (潜意识) is a perfect mental picture. We see ourselves on a long trip that

goes across the continent. We are traveling by train. Out the windows, we think in the passing scene of cars

on nearby highways, of children waving at a crossing, of cattle feeding on a distant hillside, of smoke pouring

from a power plant, or row upon row of corn and wheat, of flat lands and valleys, of mountains and rolling

hills, of city skylines and village halls.

     But uppermost in our minds is the final destination. On a certain day at a certain hour, we will pull into the

station. Bands will be playing and flags waving. Once we get there, so many wonderful dreams will come true

and the pieces of our lives will fit together like a completed jigsaw puzzle. How restlessly we pace the aisles,

condemning (谴责) the minutes for loitering (虚度)- waiting, waiting, waiting for the station.

     "When we reach the station, that will be it!"we cry."When I'm 38." "When I buy a new 450SL Mercedes

Benz!" "When I put the last kid through college." "When I have paid off the debt!" "When I get a promotion."

"When I reach the age of regent, I shall live happily ever after!"

     Sooner or later, we must realize there is no station, no one place to arrive at once and for all. The true joy

of life is the trip. The station is only a dream. It constantly outdistances us.

     "Relish (appreciate) the moment" is a good motto, actually it isn't the burdens of today that drive man mad.

It is the regret over yesterday and the fear of tomorrow. Regret and fear are twin thieves who rob us of today. 

     So stop pacing the aisles and counting the miles. Instead, climb more mountains, eat more ice-cream, swim

more rivers, watch more sunsets, laugh more and cry less. Life must be lived as we go along. Then the station

will come soon enough.
