Bert Flora’s Reviews > Flow: The Psychology of Optimal Experience > Status Update

Csikszentmihalyi (try saying that..) has written up an immense amount of research on how we live and process focus, doing and "flow". It will have you muttering a wow from time to time. It doesn't have a "how-to" direction to it. He does site sample flow that a reader can compare to their world and emulate if they so choose.
