It's a long article, well worth the read. But here are a few snippets I particularly enjoyed:
These exceptional moments are what I have called "flow" experiences. The metaphor of flow is one that many people have used to describe the sense of effortless action they feel in moments that stand out as the best in their lives. Athletes refer to it as "being in the zone," religious mystics as being in "ecstasy," artists and musicians as "aesthetic rapture." It is the full involvement of flow, rather than happiness, that makes for excellence in life.

Flow tends to occur when a person faces a clear set of goals that require appropriate responses. It is easy to enter flow in games such as chess, tennis, or poker, because they have goals and rules that make it possible for the player to act without questioning what should be done, and how. For the duration of the game the player lives in a self-contained universe where everything is black and white. The same clarity of goals is present if you perform a religious ritual, play a musical piece, weave a rug, write a computer program, climb a mountain, or perform surgery. In contrast to normal life, these "flow activities" allow a person to focus on goals that are clear and compatible, and provide immediate feedback.
Flow also happens when a person's skills are fully involved in overcoming a challenge that is just about manageable, so it acts as a magnet for learning new skills and increasing challenges. If challenges are too low, one gets back to flow by increasing them. If challenges are too great, one can return to the flow state by learning new skills.
...
Leisure time in our society is occupied by three major sorts of activities: media consumption, conversation, and active leisure--such as hobbies, making music, going to restaurants and movies, sports, and exercise. Not all of these free-time activities are the same in their potential for flow. For example, U.S. teenagers experience flow about 13 percent of the time that they spend watching television, 34 percent of the time they do hobbies, and 44 percent of the time they are involved in sports and games. Yet these same teenagers spend at least four times more of their free hours watching TV than doing hobbies or sports. Similar ratios are true for adults.
Why would we spend four times more of our free time doing something that has less than half the chance of making us feel good? Each of the flow-producing activities requires an initial investment of attention before it begins to be enjoyable. If a person is too tired, anxious, or lacks the discipline to overcome that initial obstacle, he or she will have to settle for something that, although less enjoyable, is more accessible.
