That's it, really. We've all taken the position of "Just give me my piece of paper, so I can start getting my money." In the martial arts,and Asian cultures in general, finishing basic education is looked at as a beginning, rather than an ending. When you earn a "black belt" in something, you have now mastered _the basics_, and can begin to apply those basics in real world situations, where the learning really begins and lasts a lifetime. This, to me, is a healthier attitude towards education.
Do you want to learn about Music? Audio? Production? Computers? Then you should learn, but don't expect completing a specific "belt" in one of those areas guarantees you an income. It doesn't even guarantee you'll do any better than anyone else in the field who may not be "educated." But what it will give you are shortcuts to the basic knowledge that it might have taken you years to work out on your own.
