For any given problem, if there's a simple solution it will already have been applied. So, perhaps, the solution isn't as simple as you think.
~ Stuart Aken
If knowledge is power, let's spread it as widely as possible and dilute it to deny those who would abuse it.
Knowledge, like money and muck (manure), serves us best when spread evenly.
Sell your book like a can of beans & your readers will place the same value on it.
Evil people rely on the acquiescence of naive good people to allow them to continue with their evil.
