What is Psychology?

In first place, psychology is a discipline who studies human behaviour and mental functions. It has a scientific method and an object of study: human being.
The good things about psychology is that there are many approaches inside psychology discipline, that is why there are so many things to study. What I like the most of psychology is that you can work in so many different places, becuase human beings are in almost everything.
What I dislike about psychology is psychoanalysis, because in university we had to study it in many subjects. I don't like it because I think that psychoanalysis has too many theories that are speculative and it doesn't have enough scientific support.
I think psychology is one of the most exciting disciplines in the world because it is the study of human being and it can be use everyday in human beings lifes.
