腹膜炎患者，近1个月以来常出现畏寒、发热，B超提示盆腔液性暗影3cm×4cm×3cm

     Years ago, when I started looking for my first job, wise advisers advised, "Barbara, be enthusiastic

(热情的)! Enthusiasm will take you further than any amount of experience. " How right they were!

     "Nothing great was ever achieved without enthusiasm. "wrote Ralph Waldo Emerson．It is the paste

that helps you hang on there when the going gets tough. It is the inner voice that whispers, "I can do it!"

when others shout, "No, you can’t!” It took years and years for the early work of Barbara McClintock,

a geneticist who won the 1983 Nobel Prize in medicine, to be generally accepted. Yet she didn’t stop

working on her experiments．Work was such a deep pleasure for her that she never thought of stopping.

     We are all born with wide-eye, enthusiastic wonder and it is this childlike wonder that gives

enthusiastic people such youthful air, whatever their age. At 90, cellist Pablo Casals would start his day

by playing Bach. As the music flowed through his fingers, his stooped (弯曲的)shoulders would

straighten and joy would reappear in his eyes. As author and poet Samuel Ulman once wrote, "Years

wrinkle the skin, but to give up enthusiasm wrinkles the soul.”

     Enthusiastic people also love what they do, regardless of money or title or power. Patricia Mcllrath,

retired director of the Missouri Repertory Theater in Kansas City, was once asked where she got her

enthusiasm. She replied, "My father, a lawyer, long ago told me, ‘I never made a dime until I stopped

working for money.’"

     If we cannot do what we love as a full-time career, we can as a hobby. Elizabeth Layton of

Wellsville, Kan was 68 before she began to draw. This activity ended periods of depression that had

trouble her for at least 30 years, and the quality of her work led one critic to say, "I am tempted to call

Layton a genius."

     We can’t afford to waste tears on "might-have-beens". We need to turn the tears into sweat as we go

after "what-can-be". We need to live each moment whole-heartedly, with all our senses-finding pleasure

in the sweet smell of a back-yard garden, the simple picture of a six-year-old, the beauty of a rainbow.
