Over the decades the definition of psychology has been evolving. But one thing that remained constant was studying or getting to know more about  human behaviour. 

The mankind is striving hard to develop every sector of economy. So when it was my turn to choose my field of interest, the very first thought that came into my mind was what would I be dealing with;what would be my daily routine. Then I thought, if I become an engineer I will deal with machines or automobiles and I if choose medicine I will end up studying aboit diseases and pathologies. But when I thought about psychology, I realized I will be studying about live machines-humans. Human behaviour is very complicated to comphrened, considering the fact that, all of us are different from each other. 

Later when I finally got into the field of psychology I realized, psychology is not just a subject rather it's much more than just a subject. I realized the very basic thing of humans that is drives and emotions are studied in psychology. Be it Maslow's hierarchical needs or Freud's theory of Psychoanalysis, everything has a real life application to our lives. Over the course of 4 years, I have experienced it many a times that whatever we do, what we think and bow we behave; everything falls under the domain of psychology.

The therapies that we study are systematically designed to give the best help to the human race. I still keep wondering sometimes that how diverse is this human species and how beautifully psychology tries to explain about this human diversity. For human diversity is influenced by its culture, thought process and the environment around an individual.

Psychology is not just a subject rather it's a live science that we study and understand about our actions,thoughts,feelings, behaviour and emotions better. I believe everything that we do revolves around the field of psychology.
