A major incentive (动力) for college attendance is the belief that it will prepare you for a career. Chances are that the career you want, whether in nursing, counseling, law, or management, requires a college education. Even if the return of your education isn't as great as it used to be, you would probably rather be a relatively poorly paid lawyer than a secretary or a construction worker: you would probably rather be a manager than a managee. In the sense that a degree is increasingly required for even middle-level jobs, your investment in a college education will still pay off.

It can pay off in other ways too. It is a value judgement to say that a college education will make you a better person, but it is a value judgement that the vast majority of college graduates are willing to make survey after survey to demonstrate that people feel very positive about their college education, believing that it has made them better and more tolerant people.

Whether it makes you a better person or not, a college education is likely to have a lasting effect on your knowledge and values. If you finish college, you will sit through 30 to 45 different courses. Even the least dedicated student is bound to learn something from these courses. In addition, students learn informally. Whether you go to college in you hometown or across the country, college will introduce you to a greater diversity of people than you ' re likely to have experienced before. This diversity will challenge your mind and broaden your horizons.

As a result of formal and informal learning, college graduates are more knowledgeable about the world around them, more tolerant and less prejudiced, more active in public and community affairs, and, more open to new ideas.
