Social psychology

Psychology covers lots of various subfields: from clinical neuropsychology to sports psychology. The subfield which I would like to study the most is social psychology. For this reason I took deeper interest in it, checked some literature and other information sources and found some pros and cons for this subfield.
In my opinion, the main advantage of the social psychology is to help to understand relationships between people and how they affect each other by their behavior. Nowadays it's very important thing, because for example, violence shown on TV are breaking to the streets. It sadly becomes the main subject in media.
There also exist some disadvantages of studying such subfield of psychology. The main problem is that people and their values change, so it's important to catch up and adapt to them. For example kids during the years spend their time differently, they like different things.
Even though this subfield has it's own cons, I believe that studying it honestly shouldn't seem so hard.
