【正文】 iter of his time. This was followed by _Men Without Women_ in 1927, when Hemingway returned to the United States, and his novel of the Italian front, _A Farewell to Arms_ (1929). In the 1930s, Hemingway settled in Key West, and later in Cuba, but he traveled widely to Spain, Italy, and Africaand wrote about his experiences in _Death in the Afternoon_ (1932), his classic treatise on bullfighting, and _Green H ills of Africa_ (1935), an account of biggame hunting in Africa. Later he reported on the Spanish Civil War, which became the background for his brilliant war novel, _For Whom the Bell Tolls_ (1939), hunted Uboats in the Caribbean, and covered the E uropean front during the Second World War. Hemingway39。s most popular wor k, _The O ld Man and the Sea_, was awarded the Pulitzer Prize in 1953, and in 1954 Hemingway won the Nobel Prize in Literature for his powerful, styleforming mastery of the art of narration. One of the most important influences on the development of the short story and novel in American fiction, Hemingway has seized the imagination of the American public like no other twentiethcentury author. He died, by suicide, in Ketchum, Idaho, in 1961. H is other works include _The Torrents of Spring_ (1926), _Winner Ta ke Nothing_ (1933), _To Have and Have Not_ (1937), _The Fifth Column and the First FortyNine Stories_ (1938), _Across the River and into the Trees_ (1950), and posthumously, _A Moveable Feast_ (1964), _Islands in the Stream_ (1970), _The Dangerous Summer_ (1985), and _The Garden of Eden_ (1986). Does school prepare children for the real world? Study hard and get good grades and you will find a highpaying job with great benefits, my parents used to say. Their goal in life was to provide a college education for my older sister and me, so that we would have the greatest chance for success in life. When T finally earned my diploma in 1976graduating with honors, and near the top of my class, in accounting from Florida State University my parents had realized their goal. It was the crowning achievement of their lives. In accordance with the Master Plan, I w as hired by a Big 8 accounting f irm, and I looked forward to a long career and retirement at an early age. My husband, Michael, followed a similar path. We both came from hardworking families, of modest means but w ith strong wor k ethics. Michael also graduated with honors, but he did it tw ice: first as an engineer and then from law school. He was quickly recruited by a prestigious Washington, ., law firm that specialized in patent law, and his future seem ed bright, career path welldefined and early retirement guaranteed. Although we have been successful in our careers, they have not turned out quite as we expected. We both have changed positions several timesfor all the right reasonsbut there are no pension plans vesting on our behalf. Our retirement funds are growing only through our individual contributions. Michael and I have a w onderful marriage with three great children. As I write this, two are in college and one is just beginning high school. We have spent a fortune making sure our children have received the best education available. One day in 1996, one of my children came home disillusioned with school. He was bored and tired of studying. Why should I put time into studying subjects I will never use in real life? he protested. Without thinking, I responded, Because if you don39。t get good grades, you won39。t get into college. gwilled, he has always been a polite and respectful young man. Mom, he began. It was my turn to be lectured. Get w ith the times! Look around。 the richest people didn39。t get rich because of their educations. Look at Michael Jordan and Madonna. Even Bill Gates, who 29 dropped out of Harvard, founded Microsoft。 he is now the richest man in America, and he39。s still in his 30s. There is a baseba ll pitcher who makes more than $4 million a year even though he has been labeled `mentally challenged.39。 There was a long silence between us. It was dawning on me that I was giving my son the same advice my parents had given me. The world around us has changed, but the advice hasn39。t. Getting a good education and making good grades no longer ensures success, and nobody seems to have noticed, except our children. Mom, he continued, I don39。t want to wor k as hard as you and dad do. You ma ke a lot of money, and we live in a huge house wi th lots of toys. If I follow your advice, I39。ll wind up like you, wor king harder and harder only to pay more taxes and wind up in debt. There is no job security anymore。 I know all about downsizing and rightsizing. I also know that college graduates today earn less than you did when you graduated. Look at doctors. They don39。t make nearly as much money as they used to. I know I can39。t rely on Social Security or pany pensions for retirement. I need new answers. He was right. He needed new answers, and so did I. My parents39。 advice may have worked for people born before 1945, but it may be disastrous for those of us born into a rapidly changing wor ld. No longer can I simply say to my children, Go to school, get good grades, and look for a safe, secure job. I knew I had to look for new ways to guide my children39。s education. As a mother as well as an accountant, I have been concerned by the lack of financial education our children receive in school. Many of today39。s youth have credit cards before they leave high school, yet they have never had a course in money or how to invest it, let alone understand how pound interest wor ks on credit cards. Simply put, w ithout financial literacy and the knowledge of how money works, they are not prepared to face the world that awaits them, a world in which spending is emphasized over savings. When my oldest son became hopelessly in debt with his credit cards as a freshman in college, I not only help
