“I was shaken out of my imagination by Rachel’s hand on my arm and her gentle, yet insistent, “What were you doing just now?” “Well,” I told her, “I was bringing up the picture of that scene from my movie and looking at it . . . remembering what it was like. What they looked like. How I felt. The sound of their applause.” 
“Terrific!” she exclaimed. 
“Why so terrific?” I inquired. 
“Because that, what you just did, remembering that picture in your mind, is exactly the process you use to alter any habit of belief you have on any subject, anywhere, anytime. 
“Even though these pictures are imagined, your mind accepts them as if they were real, as if they were actual experiences you’ve had and were simply remembering. 
“See,” she continued, “you’re balancing the scales, adding new images, new pictures of your new beliefs. Your mind works in geometric progression, too. It just keeps multiplying the number of times you ‘remember’ or relive the experience. In no time the scales will begin to swing the other way. 
“In fact, they have already. Once they start to pick up some momentum – even just a little – swinging in a new and opposite, positive direction, you’ll change your actions in direct proportion to your changing scales – to your changing habits of belief. Do you see what I’m saying?” 
This isn't a sales book. Or a networking book. Or even a relationships book.
Actually it's all of those, if you think about it. The Greatest Networker is a mindset book. And mindset controls everything we do, how we do it and why we do it.
The story is told in perspective-of-the-author style and his experience with a nameless, faceless business sage who doesn't directly teach him anything about how to do business... While teaching him (and the reader in turn) everything at the same time.
I watched an interview of Jordan Belfort (aka Wolf Of Wall Street) and be identified four keys to success: Vision, State Management, Belief, and Strategy. The Greatest Networker is a short, free master class on nos 1 & 3. And you can get it online at no cost. If it costs $20 it would be well worth it anyway. So go get it, read it in one day and reap the benefits.
