Positive psychology has been defined in a variety of ways and with a variety of terms, but the most widely accepted definition is as follows: "Positive psychology is the study of what makes life worth living" (Peterson, 2008). Positive psychology is a scientific approach to analyzing human thinking, emotions, and actions that focuses on strengths rather than weaknesses, creating the good in life rather than fixing the bad, and bringing ordinary people's lives up to "great" rather than concentrating exclusively on getting those who are suffering up to "normal" (Peterson, 2008). Positive psychology is concerned with positive life experiences and factors, such as: Positive encounters (like happiness, joy, inspiration, and love). Positive emotions and characteristics (like gratitude, resilience, and compassion). Institutions that are beneficial (applying positive principles within entire organizations and institutions). Positive psychology considers topics such as character qualities, motivation, life satisfaction, happiness, health, appreciation, compassion (including self-compassion), self-esteem and self-confidence, hope, and elevation as an area. These subjects are investigated to discover how to assist people in flourishing and living their best lives. The following are my questions: A. Who is Positive Psychology's founder?
