Lesson #1: Write what you don't know.
Gee-whiz, people, if you write what you know, there won't be a whole heckuva lot to write about. But if you write what you don't know, then--jeepers--there's so much more to explore. Because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say, we know there are some things we do not know. But there are also unknown unknowns; the ones we don't know we don't know.
Of course, this doesn't apply to me because there's not a heckuva lot that I don't already know.
