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

Enthusiasm will take you further than any amount of experience."

     How right they were!Enthusiastic people can turn a boring drive into an adventure, extra work into

opportunity and strangers into friends.

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

that helps you hang in 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 (遗传学家) who

won the 1983 Nobel Prize in medicine, to be generally accepted.Yet she didn't let_up on her experiments.Work was such a deep pleasure for her that she never thought of stopping.

    Author and poet Samuel Ullman 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.If we connot do

what we love as a fulltime career, we can treat it as a part－time interest, like the head of state who

paints, the nun (修女) who runs marathons, and the official who handcrafts (手工制作) furniture.

    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 wholeheartedly, with all our senses-finding pleasure in the fragrance

of a back－yard garden, the crayoned (蜡笔的) picture of a six－year－old, the enchanging, beauty

of a rainbow.It is such enthusiastic love of life that puts a sparkle in our eyes, a lift in our steps and

smoothes the wrinkles from our souls.
