According to the value fulfillment theory, our lives go well to the extent that we pursue, and fulfill or realize, our appropriate values. This chapter focuses on what values are, how they can be improved, and why we should consider them over time. To value something in the fullest sense is to have a relatively stable pattern of emotions and desires with respect to it and to take these attitudes to give you reasons for action and (for the most important values) standards for evaluating how your life is going. Appropriate values, then, are the objects of relatively sustainable and integrated emotions, desires, and judgments.
