Defining the meaning of life and the conditions, traits and features of a well-lived life is a question that throughout history engrossed theologians, philosophers, artists and, more recently, positive psychologists. This essay outlines findings from a selection of the literature and research to answer this question with the aim of identifying whether happiness is the true sign and the ultimate goal and marker of a well-lived life. This review of the literature has yielded findings that possessing a disposition towards gratitude is not only indicated to be present in a well-lived life, but can enhance and improve mental, physical and spiritual life outcomes.
The different research models used to explain, measure and identify the markers of a well-lived life are briefly outlined, and finally further research directions are indicated to expand understanding about how gratitude affects life satisfaction outcomes in specific populations. A challenge in researching this topic is that the literature describes happiness and well-lived in terms that are used by different researchers interchangeably and inconsistently. In this essay and in accordance with the literature reviewed, the terms happiness and the well-lived life are used synonymously.
Definitions
A problem with defining a well-lived life is that the terms well-being and happiness (Frey, 2011; Kristjánsson, 2010), and the good life and happiness (Dunn & Brody, 2008) are used by researchers interchangeably. Indeed Diener (2000) notes that the very term well-being has come to be known in common usage as happiness. Seligman (2011, pp 420) notes that sometimes the terms happiness and well-being define emotions whilst at other times refer to activities. This ambiguous terminology has caused some to criticize Positive Psychology but, as both Lazarus (2003) and Kristjánsson (2010) point out, precise definitions to describe a well-lived life have also eluded
