I have formed another impression in my mind. Good businessmen are naturally good story tellers. Maybe one fuels the other and one is necessary for the other, but in general, if you see a good entrepreneur, he/she will always have a good story to tell in connection with pretty much anything.

I think you need good story-telling skills in order to sell your concept well, and also you need to have a bunch of stories in relation to most of the common topics so that you can tell those stories.
