A book that I have read in English and will read again in Lithuanian.
And please don't ask to pronounce the last name of this wonderful Hungarian researcher and author. The book wonderfully describes a phenomenon that we call "letting go", "diving right in" or "in the zone". We call it many things, perhaps many things it also is.
The Flow is "optimal experience" - a state of consciousness, an experience that is genuinely satisfying. During flow, people typically experience deep enjoyment, creativity, and a total involvement with life. The Flow 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.
