Getting a good education is more important than every before. First more and more people are going to college. This means if you don't go to college you are already way behind. Secondly, technology has improved vastly and it is the wave of the future. If you avoid becoming educated on these technological advances you will be left behind.
Getting a good education is not necessary for a successful future. An education can improve your chances of having a successful future, however there are successful people without good educations in their background. There are also many people who have obtained a good education only to find that they can not find work in their field.
