                                                Success Is Not a Destination (目的地)

     Should people stop once they have achieved something? No! In life, they are always trying to make

things better or have more of the same success.

     Athletes are constantly striving (努力) to shorten time for races, increase heights or distances.

     The world of medicine has had its series of successes, too. Christian Barnard performed several

successful heart transplants. Other medical experts have achieved organ transplants. Throughout the

ages, mankind has found treatments and cures for cancer and other diseases. A cure for AIDS might

soon be discovered.

     Age does not seem to slow down achievers. Tina Tuner at 54 is still singing in abundance (丰富)

and attracting sell-out crowds wherever she goes.

     Comedian George Burns, in his 90s, wants to perform at Caesar's Palace when he turns 100.

     Success does not belong only to the rich and famous. It should be the goal of everyone. Many

successful people have had humble beginnings.

     Would you believe that actress Michelle Pfeifer of Cat was a supermarket checkout girl?

     At work, we strive for achievement, too. Success may mean organizing a conference more effectively

and efficiently each year. Sometimes, it is not a pat on the back or the promotion that makes it worthwhile.

     Often, it is the inner thrill (一阵激动) and satisfaction of achievement, no matter how small it may be.

     Aiming for success doesn't mean you are greedy or dissatisfied. It is all part of gaining new experiences.

It ultimately (最终) makes you a more interesting and useful person in society.

     The journey to success has its road blocks, discouragement and distractions. It takes great resourcefulness

and achievement to overcome obstacles and setbacks to move on successfully.
