Years ago, when I started looking for my first job, wise advisers told me, “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 was ever achieved without enthusiasm.” wrote Ralph Waldo Emerson.①.    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 Mclintock, a geneticist who won the 1983 Nobel Prize in medicine, to be generally accepted. Yet she didn’t stop working on her experiments.    ②   
We are all born with wide-eyed, enthusiastic wonder and it is this childlike wonder that gives enthusiastic people such a 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 shoulders would straighten and joy would reappear in his eyes.    ③ As author and poet Samuel Ullman once wrote, “Years wrinkle(起皱纹) the skin, but to give up enthusiasm wrinkles the soul.”
How do you rediscover the enthusiasm of your childhood? The answer, I believe, lies in the word itself. “Enthusiasm” comes from the Greek and means “God within”. And what is God within is but a sense of love---proper love of self(self-acceptance) and, from that, love of others.
④     If we can’t 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 troubled her for at least 30years, and the quality of her work led one critic to say, “ I am tempted to call Layton as a genius.”
We can’t afford to waste tears on “might-have-been”. 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 backyard garden, the simple picture of a six-year-old, the charming beauty of a rainbow.
