"Act well your parts; there all honor lies".

This quote means that if you are good and no one has to tell you to do it you will feel better. If you do bad you will just fell bad about yourself. You would not want to do the wrong thing in the first place. If you do everything correct by step. People are not going to come up to you and tell you that you did it wrong. Some people my not follow the rules and still think they did a wonderful work. But at the same time its wrong because they did not follow the steps. It is good that people come up to you and say you did a good job.
