My daughter got a degree in Communications about 5 years ago. Absolutely useless, but she would not listen to good old dad. Had to find out the hard way. All she got for her effort is a large student loan that she is still paying back.
A few years ago I read a report in a business magazine saying that the ability to communicate clearly was the single most sought after skill and the hardest to find. That probably means you don’t learn that in communications classes.
I don’t know how much truth there was in that report but I am certain that the ability to communicate clearly is indeed rare. I suspect that it is something that you are born with rather than something that is learned in school.
