[https://en.wikipedia.org/wiki/Flow_(psychology)
"In positive psychology, a flow state, also known colloquially as being in the zone, is the mental state in which a person performing some activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity. In essence, flow is characterized by the complete absorption in what one does, and a resulting transformation in one's sense of time.[1] Flow is the melting together of action and consciousness; the state of finding a balance between a skill and how challenging that task is. It requires a high level of concentration, however; it should be effortless. Flow is used as a coping skill for stress and anxiety when productively pursuing a form of leisure that matches one's skill set.[2]"
