Unlike traditional psychology that focuses more on the causes and symptoms of mental illnesses and emotional disturbances, positive psychology emphasizes traits, thinking patterns, behaviors, and experiences that are forward-thinking and can help improve the quality of a person's day-to-day life. These may include optimism, spirituality, hopefulness, happiness, creativity, perseverance, justice, and the practice of free will. It is an exploration of one's strengths, rather than one's weaknesses.

The goal of positive psychology is not to replace those traditional forms of therapy that center on negative experiences, but instead to expand and give more balance to the therapeutic process.
