"He Who Can Do This Has The Whole World With Him. He Who Cannot Walks a Lonely Way"

Why talk about what we want? That is childish. Absurd. Of course, you are interested in what you want. You are eternally interested in it. But no one else is. The rest of us are just like you: we are interested in what we want. So the only way on earth to influence other people is to talk about what they want and show them how to get it.

Every act you have ever performed since the day you were born was performed because you wanted something.

Tomorrow you may want to persuade somebody to do something. Before you speak, pause and ask yourself: "How can I make this person want to do it?"

"If there is any one secret of success, it lies in the ability to get the other person's point of view and see things from that person's angle as well as from your own."

Thousands of salespeople are pounding the pavements today, tired, discouraged and underpaid. Why? Because they are always thinking only of what they want. They don't realize that neither you nor I want to buy anything. If we did, we would go out and buy it. But both of us are eternally interested in solving our problems. And if salespeople can show us how their services or merchandise will help us solve our problems, they won't need to sell us. We'll buy. And customers like to feel that they are buying – not being sold.

The world is full of people who are grabbing and self-seeking. So the rare individual who unselfishly tries to serve others has an enormous advantage. He has little competition.

Looking at the other person's point of view and arousing in him an eager want for something is not to be construed as manipulating that person so that he will do something that is only for your benefit and his detriment. Each party should gain from the negotiation.
