Self-publishing on Amazon is easy; I did it twice as an experiment and once you get the proper text conversion tools, and have already collected it together, reformatting it to fit the proper form for an electronic book and going through the steps necessary to get it “out there” in a book form, only took me 45 minutes on the second try.
There’s great satisfaction to seeing it “up there”, as for some people, “I wrote the book on the subject” is enough to soften their contradictions and, if not gaining a believer, certainly gaining someone who says, “This guy might be onto something here. He wrote a book.”
and… that’s pretty powerful to have.
