Hey, now, he did quote Henry Ford too, one of AWAI's top graduates!

I'll add one from PT Barnum: "There's a sucker born every minute."
Do I think AWAI students are suckers? Heck no, I'm one, too! My AWAI course notebook gave me a lot of great advice, "got me off of my ass", and now occupies a shelf alongside my Carlton, Vitale, and Ogilvy books. I've learned a lot of valuable lessons from all of them. There's no harm in AWAI, provided the consumer realizes that there are countless other copywriting resources out there that will also provide quality instruction.
BTW, nothin' I love better than a drive-by poster that delivers pithy (read "worthless") advice then disappears. I can always use a good laugh.
