Someone told me as a writer you are best to write about what you know best. If you adlib, the readers will know you're a phony. That kind of narrows things down for me, because as a writer what I know best is limited - limited, that is, to education and aviation. Most of my years have been spent in that area of expertise.
Oh, I have done a lot of things in my lifetime other than education and aviation. I guess you could say I'm somewhat experienced in raising children. I've had four children, but so has everyone else, so who wants to know about rearing children? Boring.
