This book is about all the exciting aspects that have been investigated in the science of positive psychology. One of the reasons that the interest in positive psychology has increased so much in recent years is that people are interested in happiness, and they’re interested in enhancing their well-being. All conceptions of positive psychology involve something to do with the “positive side of life”, which is clearly contrasted with the negative side of life. The positive side of life seems to go by many names, such as happiness, flourishing, thriving, a worthwhile life, a meaningful life, a fulfilling life, or “what goes right in life”. The study of positive subjective states involves two related but distinct areas of study: positive emotions and subjective well-being (SWB). Positive psychologists often refer to two types of happiness: hedonic and eudaimonic. Any treatments of the history of happiness spend little time on ancient Jewish contributions to our understanding of well-being. From the early Christian tradition, writers encouraged enduring suffering now in the light of future happiness in the afterlife. The book focuses on two theories that are both representative and helpful to the field of positive psychology: the Self-Determination Theory (SDT) and the Hedonic Adaptation Prevention (HAP) model. Gratitude and compassion are very important to the good life; however, when we also emphasize strengths such as prudence, humility, self-control, and integrity, we are much more likely to flourish. The issue of Internet relationships also brings up an alternative form of relationships: Our relationships with our pets. The book attempts to describe the cognitive characteristics of happy people.
