How many people have I met who have told me about the book they have been planning to write but have
never yet found the time? Far too many.
This is Life, all right, but we do treat it like a rehearsal (排演) and, unhappily, we do miss so many of its
best moments.
We take jobs to stay alive and provide homes for our families always making ourselves believe that this
style of life is merely a temporary state of affairs along the road to what we really want to do. Then, at 60 or
65, we are suddenly presented with a clock and several grandchildren and we look back and realize that all
those years waiting for Real Life to come along were in fact real life.
In America they have a saying much laughed at by the English: "Have a nice day" they speak slowly and
seriously in their shops, hotels and sandwich bars. I think it is a wonderful phrase, reminding us, in effect, to
enjoy the moment: to value this very day.
How often do we say to ourselves, "I'll take up horse-riding (or golf, or sailing) as soon as I get a higher
position," only to do none of those things when I do get the higher position.
When I first became a reporter I knew a man who gave up a very well paid respectable job at the Daily
Telegraph to go and edit a small weekly newspaper. At the time I was astonished by what appeared to me to
be his completely abnormal (反常的) mental state. How could anyone turn his back on Fleet Street in central
London for a small local area?I wanted to know.
Now I am a little older and possibly wiser, I see the sense in it. In Fleet Street the man was under continual
pressure. He lived in an unattractive London suburb and he spent much of his life sitting on Southern Region
trains.
