to listen to what people say to you. It is easy to misunderstand what they say. Take the poor tin man here. He was supposed to be the smart one.... he should have thought a little more carefully about what Dorothy was asking of him. It is easy to just respond to what someone says without thinking it through all the way. Sometimes I do that and it isn't always so good. Take time to really listen to people. Think first, act second. Its a pretty good rule to live by. After all, who wants to eat straw?
