How about "rules of thumb"?
On several occasions I have read passages of Guy Kawasaki's book, Rules for Revolutionaries, but just today completed a thorough re-read of the book. It is even better than I remembered! Of course it was a birthday present to myself... twelve years ago!
If you haven't read it, you should. If you have, you might want to consider re-reading it.
Then maybe we have something in common to talk about. {grin}
