A question?

Seeings how i forgot to submit a question before class last week i must do it now and try to answer my own question. My question is "What does all this have to do with Psychology?" Alot of what i read was just a refresher of last semesters psych class. The id and the ego, what makes us do what we do? I understand that all the things we do in todays world has an answer for it. What we do everyday defines who we are as people and that is where psychology comes in. We are trying to determine how our minds work and what we do that makes our minds work the way they do. I really don't have much of an answer for my own question right now except that i suppose you can find psychology in everything we do. It is all about how how we think that determines what we do.
