““My simple rule was that, whenever I met someone, I would try to do something for them. It might simply be an introduction to someone else or even just a sincere compliment. What was intriguing to me was the way they reacted. In some cases, I sensed that they were saying to themselves, “That’s nice. I wonder what else this guy is going to do for me, or what else I can ask him for.” In other cases, I could see that they wanted to help me too. These seemingly trivial interactions provided a barometer of whether people approached the world as givers or takers.””
