I was just on Amazon reading reviews of Joe Vitale's awesome book, Life's Missing Instruction Manual (I do that with books I love to see what others thought).
One of the reviews used the term "Internet celebrities" to describe Dr. Vitale's friends and colleagues who contributed to the book.
I found this interesting because they didn't have to get a lucky break in Hollywood or become rock stars to become Internet celebrities. All they did was build a web presence that positions them as the expert. And guess what - that's the same exact advice I tell salespeople who want to become top producers: build a web presence that positions you as the expert. Contrast that with cold calling, which just makes you look like an idiot.
There's a myth that "It's not what you know, it's who you know." People think connections are the most important thing. That's a half-truth. As Jeffrey Gitomer said it so well, "It's not who you know, it's who knows YOU that matters."
