Describe a time (or several) when you experienced "flow"

• In flow, goals are clear. You have to reach the top of the mountain, hit the ball across the net, or mold the clay just right. Feedback is immediate. The mountaintop gets closer or farther, the ball sails in or out of bounds, the pot youre throwing comes out smooth or uneven.

• Most important, in flow, the relationship between what a person had to do and what he could do was perfect. The challenge wasnt too easy. Nor was it too difficult. It was a notch or two beyond his current abilities, which stretched the body and mind in a way that made the effort itself the most delicious reward. That balance produced a degree of focus and satisfaction that easily surpassed other, more quotidian, experiences.

• In flow, people lived so deeply in the moment, and felt so utterly in control, that their sense of time, place, and even self-melted away. They were autonomous, of course. But more than that, they were engaged."
