THREE PHASES TO AN ENJOYABLE LIFE
When I was a boy, I would watch the space launches on TV. The rockets were in three phases. As it got so high, the lowest section of the rocket would drop off. Then the second section would drop off until only the capsule would remain. It took all three sections to have a successful manned space launch.
An enjoyable life is similar. There are 3 elements that affect how much we enjoy life: happiness (which is often dependent upon friends and social participation), meaning (which is dependent upon purpose), and positive experiences: events, the arts, sports, hobbies, interests, or thrills, which give us "lifts" in varying degrees.
