Exploring The Idea of Contentment Through the Lens of Positive Psychology:
In many ways, Contentment, which can be defined as the state of being satisfied, can be closely associated with the concept of happiness. In Positive Psychology social scientists study what might contribute to living a good life, or what would lead to people having increased positive mood and overall satisfaction with their life. 

Happiness, in Positive Psychology, is defined in a twofold manner, which in totality is referred to as Subjective Well-Being. How much positive emotion (Positive Affect) as opposed to negative emotion (Negative Affect) does a person have, and how does one view one's life overall (global satisfaction) are the questions asked in Positive Psychology to determine Happiness. 

Maybe Contentment could be more associated or closely related to a person's level of satisfaction with his/her life (global satisfaction), but nevertheless the idea of Contentment is certainly intertwined in the concept of what makes people happy. Positive Psychology finds it very important to study what contributes to people being happy and to people flourishing, and finds it just as important to focus on the constructive ways in which people function and adapt, as opposed to the general field of psychology which focuses more on what goes wrong or is pathological with human beings...

What The BIBLE Says About Contentment:
