Good education is a passport to an individual's success and happiness, which is nowadays considered to be absolutely right. However many people don't know what the real definition of one person's education is and how long it should lasts. They simply interpret their process of education as going through the elementary school, the middle school and at last the university. Then they find a job and think that their education thus comes to an end. Since then their process of education is over.
The notion is widespread among people and superficially it is without doubt. But actually it's an utter misconception. Education provides us with various knowledge on various areas. It is these knowledge that makes us sensible, reasonable and able. Education supplies us with an opportunity to develop the ability to deduce, judge and make correct decisions. It is this ability that makes us become confident, daring and perceptible persons.
But, we cannot soak up all of the knowledge at one time. It is impossible for an individual to learn all the knowledge created by generations of humans. However, we can enrich our knowledge gradually and incessantly to guarantee that our knowledge can help us survive the fiercely competitive world. It's a very pressing and realistic problem. In this world, every day there are some people that lose their jobs sometimes because their education, their knowledge, cannot be sufficient to make them qualitied for their job. And even if people have already had sufficient knowledge of one specific area, that's not enough. Nowadays, the speed of production and creation of new knowledge is becoming faster and faster. New more advanced knowledge are replacing old, obsolete knowledge. Some people call it "the explosion of knowledge". 
Then, if you want to hold your job and enjoy a comfortable life, you should take the initiative in learning new knowledge on the particular area we're engaged in to make yourself keep up with the times. Because the development of the society and your job demands that you "charge" yourself now and then. Or else, you will be eliminated from the crowded competitors. 
In America, one of the characteristic of the society is job mobility. People will not stay in one company for life. They frequently change their jobs. But changing jobs is not actually easy. Different jobs need different knowledge and capability. If you just excel perticularly in one subject, and do poorly in other aspects, you are unlikely to change jobs as frequently as those with versatile talents. And now, the job mobility is increasingly widespread, and the economic environment fluctuates all the time, so each of us faces the potential danger of losing our jobs. Thus in order to secure a good job and in order that we can change our jobs to meet the changing economic enviroment, we should always keep ourselves educated 
So education is a lifelong process, we have to educate ourselves all our lives for our well-being.
