How does Oedipus connect to The meaning of Life?

I feel like the most important messages learned from Oedipus are to not take situations or people at face value and to think about what you are going to say before you say it. In life, peoples' impressions of you are formed by the way you act and speak. Oedipus essentially curses himself when he says that whoever killed his father will be banished from the kingdom, because he doesn't realize what is truly going on. If he hadn't been so rash in his decision making, the story could have ended differently. This plays off my current theme of other peoples' opinions and the impact you leave in the world once you are gone; Oedipus is a classic example of a greatness to tragedy situation, he is a king at one moment and an outcast the next. Taking what he saw before him: his wife, his home, and his children for face value was also a mistake. Seeing the peculiar circumstances that caused him to marry his own mother and the effect that had made me realize to make sure I know what I am getting myself into before I do it, sort of like a "think before you act" effect. Oedipus had all the necessary qualities to be a great leader, but his unwillingness to observe the facts presented to him by various friends and messengers led to his demise. I feel like another aspect to a meaningful life is to be a respectful person through courtesy and a willingness to withhold on making judgments about others until you truly know them and their individual situation, because rushing into situations can end up badly in the end.
