Answer: control
Psychology has several goals, and the last one of these is "control." This does not mean controlling others, but controlling your own behaviour. When we study the human mind, our ultimate goal is to improve the lives of these same people, and the way we can achieve them is by helping the patient make constructive and influential changes in his behaviour and ultimately his life.
