Very few folk that I have worked with lately have come used all the elements of any degree course they undertood in their late teens and early twenties. Some of the most successful entrepreneurs in the world have made it to the very top of their sphere by not actually going to university at all. I can think of at least 3 youngsters today who flatly refused – knowing how school beat them down into difficult, tetchy teenagers. All 3 have made fantastic business successes and unless anything goes seriously arry, will probably never regret their decision to abandon the formality of learning. They will say that everything they know to be of use to them now has been learnt out there in the work place, on the job.
That may not be the case for most folk, who must constantly upgrade their knowledge, either for their current job or for personal advancement in other fields. Online courses offer a whole world of door openings!
