A psychological model suggests that the most profound happiness comes from integrating three key areas into one's life: experiencing positive emotions (pleasure), being deeply absorbed in challenging activities (engagement), and serving a cause larger than oneself (meaning). Considering this model, which of the following individuals is most closely living a 'full life'?

An individual is a highly successful CEO who enjoys a luxurious lifestyle with fine dining, exotic vacations, and expensive hobbies. They are also recognized as a master of their craft, finding deep engagement and a state of 'flow' in their complex work tasks. Despite these successes, they report a persistent feeling of emptiness and a sense that their life lacks a larger purpose. According to the framework for achieving a 'full life', which component is this individual most clearly neglecting in their pursuits?
