A few psychology questions that I'm hoping you can help answer?

Psychology is the study of human behaviour and tries to determine why we do what we do. It involves behavioral patterns, different personalities, who people hang out with and why, what people were subjected to as children, what they were subjected to educationally which all contribute to the value of Psychology. It also involves how they respond to the media and world in general and why. It all comes down to the statement "As a man thinks so he is!" Be it positive or negative that is how people are and what Psychology tries to uncover is why people do what they do and what motivates it. It tries to find solutions that are positive and good and to steer people into the right direction. It requires an absolute understanding of mankind and a special type of wisdom to find a solution to a troubled mind and therein (the troubled mind) lies the tale. One has to find a sensitivity and wisdom for every unique situation in relating to the person involved so as to be able to find a way to help each situation allowing it to not influence your own life and become a part of it, almost distancing yourself as a protection yet being positively influencial in the person's life. One has to find a happy medium.
