Even if they don't know it consciously, people can feel when you are making them into a means to an end only. And people are much less likely to do what you want them to do - for example, to buy the car - when they feel you are reducing them into a means to an end.
Eckhart TolleFor some people, it's the beginning of an awakening when they hear or read, "You have a voice in your head that never stops talking. Have you noticed that?" And suddenly they become aware that the thoughts go through their heads, whereas before they were so identified with them that they were those thoughts.
Eckhart Tolle
