Mihaly Csikszentmihalyi in 1996 on the concept of Flow:

[Flow] is being completely involved in an activity for its own sake. The ego falls away. Time flies. Every action, movement, and thought follows inevitably from the previous one, like playing jazz. Your whole being is involved, and you’re using your skills to the utmost.

Goals transform a random walk into a chase. You need clear goals that fit into a hierarchy, with little goals that build toward more meaningful, higher-level goals. Here you are, tracking the footprints of some animal you haven’t seen. That’s exhilarating. Then there’s the question of feedback. Most Web sites don’t very much care what you do. It would be much better if they said: “You’ve made some interesting choices” or “You’re developing a knowledge of Picasso.” There’s also the ability to challenge. Competition is an easy way to get into flow.

Realize that change and downtime are important. I found that if a painter relates to objects only through vision, his work is much less original than a painter who walks up to the object, smells it, throws it in the air, and manipulates it. The variety of sensory inputs allows you to create a visual image that has all kinds of dimensions bubbling up inside it. We are still a multimedia organism. If we want to push the envelope of complexity further, we have to use all of our devices for accessing information – not all of which are rational.
