First of all, in psychology there is a mood. A mood is an emotial state. It can be something positive or negative. Why positive? Because it can be caused by many different aspects of life. Good mood is usually considered a state without an identified cause; people can not explain exactly why they are in a good mood. It seems to be when they had a good night sleep, and feel no sense of stress in their life. Also, when they do sports because it can reduce depression. Why negative? Because it can have an important implication for human mental and physical well being. Also, negative moods can affect an individual’s judgment and perception of objects and events. It is mostly related to depression, anxiety, physiological stress and aggression.
Second of all, self-esteem is an aspect really important in life. It can be high or low. People with high self-esteem believe in certain values and they are always ready to defend them. These people are not feeling guilty when others don't necessary like their opinion or choice. They enjoy a lot of activities in life. People with low self-esteem can result from different factors like genetic, bullying, physical and weight appearance. These people used to criticize themselves and always to strive for perfection but sometimes they do not reach this perfection.
Third of all, in psychology the term motivation nominate the orientation of emotions of a person to his goal. Often people will choose between the action or rest. They will not be motivated to go search for help beside a psychologist. This hierarchy shows that the more we increase level the more motivation becomes very important. First, the humain need to take care of his physiological needs (eat, drink, sleep). After that, he needs to feel safe with people around him and the place where he lives. He must feel loved by others to finally reach the top with confident. In other words, motivation is a logical sequence.
For conclusion, psychology is a very large program of study but still studied human behaviour. The mood, the self-esteem and the motivation are the three important concept in that field. Psychology will always be a subject interesting because as I said it gave importance to the various human behaviours because each individual has emotions, thoughts and a way to act differently.
