Do you ever think why we do such things or why we are so willing to spend time to do that thing? Psychology has explanation regarding this things.

The best word to explain that thing is because we are motivated. Motivation is defined as the process that initiates, guides, and maintains goal-oriented behavior which causes us to act. It involves biological, emotional, social and cognitive forces that activate our behavior. In our everyday life, motivation is used to describe why a person does something. 

Anyone of us has a goal, like for example to become one of the dean's lister of your school. Achieving this goal requires the ability to persist obstacles and difficulties in achieving such goal. 

Motivation have three major components.

1. Activation which involves the decision to initiate behavior, example of this is enrolling in chmsc as physical science student.

2. Persistence which is the continued effort toward a goal even though obstacles may exist, example is pursuing to become a physical science student in CHMSC even though you may encounter different challenges things like exams and interviews.

3. Intensity which can be seen in the concentration and vigor that goes into pursuing a goal.

So what are the things that motivate us to act? Psychologist proposed different theories to explain motivation 

1. "Instinc theory". It is the fixed and inborn pattern of behavior that are not the result of learning or experiences. 

2. "Extrinsic theory". Are those that arise from the outside environment of an individual and often involve rewards, social recognition and praise.

3. "lntrinsic theory of motivation". It arises from within the individual.

4. "Incentive theory of motivation". It tells that our behaviors are driven by the external rewards. People are pulled toward behavior associated with positive incentives and pushed away behaviors associated with negative incentives.

5. "Arousal theory of motivation". People are driven to perform actions in order to maintain an optimum level of physiological arousal.

Practical application:

Courting a girl is one of the easiest yet in time example of how we are motivated. In order to get the attention and the heart of a girl that you love which doesn’t love you, you need to work hard in courting her right? Doing different things such as giving her chocolates, flowers, gifts and specially your attention will be a great effort which may attract her. Because of that efforts the girl love you back and give her "YES" to you. There, the application of the extrinsic theory of motivation happens. All the effort you gave in courting her was rewarded by her "YES".
