Intentional activity is defined as “actions or practices in which people can choose to engage ...[and which] require some degree of effort to enact” (Lyubomirsky, Sheldon, and Schkad 2005, 118); the researchers suggest that this concept might contribute to an individual’s discovery of sustainable happiness. More closely examining aspects of intentional activity, one key idea that appears is “person-activity fit,” which refers to choosing an activity that fits an individual’s “strengths, interests, values, and inclinations that undoubtedly predispose them to benefit more from some strategies than others”(122).Two important features of maintaining an activity on an ongoing basis are finding meaning and value in the activity and varying its practice.
