Why do I do things?

I have no idea what we did in the last class, but that did not prevent me from wondering, "Why do I do some of the things I do?". I really hate doing some of the stuff I do but still, I do it anyways. Some of the reasons are obvious, doing school work to get a grade, doing my laundry so I have clean clothes in the morning or working out so I don't get fat and lose my delicious beach body. And there are harder ones, hanging out with people to gain social acceptance, putting up with things you don't like because other people think it's okay or even giving up things for some sort of random religious significance. All together I wish I could just do whatever I want, but unfortunately to live as I would like too it is necessary to act in a certain way to appease others.
