Is It Possible for People to Increase Their Happiness Levels?

The absence of happiness does not mean that some one is experienced suffering a mental disorder. We tend to overestimate the extent to which positive experiences will bring po emotions, and also overestimate the degree to which negative experiences will bring negative emotions. People are not very good at knowing what will make them happy. And we have all these stories that we tell ourselves with things that we think are going to make us happy.
