One thing that I will remember from this semester of psychology is the classification of Obsessive-Compulsive Disorder, or OCD for short. I will remember this most because I have it. However one useful thing that I will take out of this reading that I don't have it as bad as the book says is possible. I like to do things in threes and fives and if I can help it I will. However I am not so extreme where I can only do things in those two numbers. Another thing the book mentioned is that these people tend to repeatedly check door locks and such and this especially related to me because I constantly worry that I haven't locked my door.
Other than the common "rituals" that people with OCD suffer from I learned the most that I wasn't as extreme which helps me because it can be easily treated. Since my OCD is not that extreme I could easily overcome it by gradually decreasing the extent to which my OCD affects certain areas, much like the idea of extinction. With that I could start to lose this habit and that is one thing I will remember because it affects me daily.
Overall I would say I learned I should try to keep this under control or try to get rid of it completely, the first one being a more obvious and easier choice. And once again since this affects me daily, I will remember this in the next 5 years.
