Flow

"The optimal state of inner experience is one in which there is order in consciousness. This happens when psychic energy or - or attention - is invested in realistic goals, and when skills match the opportunities for action. The pursuit of a goal brings order in awareness because a person must concentrate attention on the task at hand and momentarily forget everything else. These periods of struggling to overcome challenges are what people find to be the most enjoyable times of their
lives. A person who has achieved control over psychic energy and has invested it in consciously chosen goals can not help but grow into a more complex being. By stretching skills, reaching toward higher individual challenges, such a person becomes an increasingly extraordinary individual."

Yes!!!
This is excellent. A perfect expression of something I had been trying to put to words.
