In modern society everybody is supposed to receive education so as not to squeezed out of job markets. As the mankind is progressing, more and more talented men are needed. If you don't receive much education, you are in danger of being rejected by society. So education is a lifelong process.
When you are born, you are too young to receive much knowledge. But as time goes. You are learning more and more knowledge, both from the experiences of everyday life and the education from schools. No one can escaped from being educated so long as he is in touch with the human community. Otherwise he should have be rejected already. So the days before you get a job is quite an important time for you to receive education.
Does it mean you needn't receive education when you've got a job already? The answer is no. Since it is so difficult getting or keeping a job, you have to receive education all the time so as to make yourself more competitive. That's one thing, and for another with much education can keep you going with the time, not to be rejected. And moreover, it can help you enjoy life better. You can solve problems more easily in many different ways. You can receive more respect and etc.
It is just like what Darwin said, "Those who suit, survive." If you abandon being educated, you'll be abandoned by society. So, please do remember, if you want to live better, keep your education a lifelong process.
