I have the opposite probem to Donuel. My tendency is to say... or type... long explanations of my ideas & opinions, with explications of the explanations as I go. There never seems to enough time or words to adequately explore all the byways.

When I was in graduate school, we had 2 hour seminars. My favorite philosophy professor was always surprised when someone noted the class time had expired..... he had this web of interlocking concepts and clarifications in his head, and there was no obvious place to stop. I empathasize with him.
Sadly these days, many kids don't want that long version of ANY area of study, and education 'seems' to be cooperating.
