I took Introduction to Psychology for this goal. I chose to take it as a summer class, and it was one that oddly only lasted for two weeks. Although it was a lot of work to do in a short time span, I learned a lot from the class ad was able to relate a lot of it to my personal life. Psychology is one of those classes that everyone should take at least once in their life. It teaches you so many interesting things about yourself and about your mind that you would never know otherwise.
