We all want to be happy. According to recent analyses of the self-improvement market in the U.S. alone, as much as $549 million per year is spent on self-help books, and self-improvement as a whole could represent a $10 billion per year industry. But what are the actual psychological components that define happiness?
Since 1998, a new field of study has sought to answer this and other questions about human behavior. Positive psychology is "the scientific study of what makes life most worth living," and it examines the biological, personal, relational, institutional, cultural, and global dimensions of life. The goal is to understand how to achieve eudaimonia, a Greek word which refers to a contented state of being healthy, happy, and prosperous.
