Thought means life, since those who do not think so do not live in any high or real sense. Thinking makes the man. – Amos Bronson Alcott

Thinking more than others about our own thoughts is not self-centeredness. It means that if asked whats on our mind, we are less likely to mention being aware of the world around us, and more likely to mention our inner reflections. But we are less likely to mention thinking about other people. – Elaine N. Aron
