Gracious. I was replying in general terms to a general comment about starting a business. There was nothing mentioned in Dennis' post about Internet Marketing, just that a nameless person had read a lot of books on marketing, advertising, etc, and was thinking of starting a newsletter. I read a lot of those kind of books in university as a requirement to get a marketing degree, and still read everything I can. And I never got into Internet Marketing even though I've had a presence on the web since early 1995. Most of my work is offline.
But who am I to tell someone they can't be an Internet Marketing Expert? (I'd love to see someone come along and present an entirely new approach that isn't like everyone else's stuff.) After all, #4 of my 12 principles is "Position yourself as the leader in your niche, not a follower or an also-ran."
But it seems from all I've read, quite successful people learn lots from their mistakes and failures. So let 'em fail.
Some people don't listen to naysayers, anyway. Heck, if it weren't for Mrs. Sauers, my grade 11 english teacher who said I'd never get published, I might not be making a living today from sales of books I've written! ;>)
