It is probably true to say that most people believe that a university degree is the only way to get a good job. I think this is true in certain areas, while in other areas, a degree is not as useful.
To begin with, many people have ambitions to become a qualified professional and there is no doubt that becoming a doctor or a lawyer, for example, is only possible with a degree. Another advantage of graduating from university is that it when it comes to choosing a job. Most employers will be more impressed by a candidate who has a degree than they would be by one who only has high school qualifications because it shows a certain level of intelligence and education, as well as the commitment and self-discipline that is needed a degree course for three or four years.
On the other hand, there might be some benefit to starting your career early, especially if is one which does not typically require a university education. This would apply to somebody who wants to be a for instance, who would not necessarily gain anything from going to university. while others are studying for a degree can give you a distinct advantage. I once read about a man who left school at sixteen and went on to become a wealthy and successful investment broker. He claimed that he had learned all he needed to know by working in his chosen field and that he could not have done any better by getting a degree.
So, to conclude, it is possible to get a good job without going to university. Having said that, some professions, such as the law, require you to have a degree and as degree could potentially open more doors when looking for a job.
