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 isthe paste that helps you hang on there, then 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-eyed, 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 shoulders would straighten and joy would reappear in his eyes. An 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 Mellrath, 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 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 30 years, and the quality of her work led one critic to say, "I am tempted to call Layton a genius. "

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.

A few months ago as I wandered through my parents’ house，the same house I grew up in，I had a sudden，scary realization．When my parents bought the house，in 1982，they were only two years older than I am now．I tried to imagine myself in two years, ready to settle down and buy the house I’d still be living in almost 30 years later．

It seemed ridiculous．On a practical level，there’s no way I could afford to buy a house anytime soon．More importantly，I wouldn’t want to．I’m not sure where I’ll be living in two years，or what kind of job I’ll have．And I don’t think I’ll be ready to settle down and stay in one place．

So this is probably the generation gap that divides my friends and me from our parents．When our parents were our age，they’d got their education，chosen a career，and were starting to settle into responsible adult lives．

My friends and I--“Generation Y”--still aren’t sure what we want to do with our lives．Whatever we end up doing，we want to make sure we’re happy doing it．We’d rather take risks first，try out different jobs，and move from one city to another until we find our favorite place．We’d rather spend our money on travel than put it in a savings account．

This casual attitude toward responsibility has caused some critics to call my generation “arrogant”(自大的), “impatient”, and “overprotected”．Some of these complaints have a point．As children, we were encouraged to succeed in school，but also to have fun．We grew up in a world full of technological innovation: cell phones，the Internet，instant messaging，and video games．

Our parents looked to rise vertically(垂直的)--starting at the bottom of the ladder and slowly making their way to the top, on the same track, often for the same company. That doesn’t apply to my generation.

Because of that, it may take us longer than our parents to arrive at responsible, stable adulthood. But that’s not necessarily a bad thing. In our desire to find satisfaction, we will work harder, strive for ways to keep life interesting, and gain a broader set of experiences and knowledge than our parents’ generation did.
