I heard it stated as three groups:
Those who enjoy talking about things.
Those who enjoy talking about other people.
Those who enjoy talking about ideas.
Everything else is pretty much corollary.
Yeah, I think they do, kind of sort of.
I just sent my kid off to college, to get a degree in business.
I sent him with a hot-dog machine.
See, there is talking, and doing...
He is learning (I hope, I cringe), but he is also selling hot dogs, and making a fortune at it...
