Ok. Psychology is interesting, fun, and all that good stuff. But you asked if it is "worth" studying; ie. worth the time and money. In my humble opinion, psychology almost never pays off career-wise or financially. If you want to study it, you had better get a PhD. If you will not go that far in your education, psych is a waste of time. You cannot do anything in the field without a PhD or at the very least a Masters. Sure, you can get a $30,000 per year job at JohnQ, Inc. as a human resources specialist or some equally boring job. My biggest problem is that, for the majority of people, pyshcology positions do not pay well. The average psychologist (PhD) earns about $55,000 per year. I would never invest the time, effort, and money to pursue psychology when there are a plethora of other fields which pay much better.
