I've seen that many gurus and non-gurus alike in their training videos or, sales letters, or reports or whatever, when they show their proof of earnings or how they do something at a site, they often say something among the lines of "And this is just one of my many (facebook, clickbank, ezinearticles, whatever...) accounts"
My question is, why do they have more than one account?
Is it for the sake of organization? Or are there other reasons?
Can someone tell me if they know?
