Flow is the mental state of operation in which a person performing an 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 complete absorption in what one does. Proposed by Mihály Csíkszentmihályi, the positive psychology concept has been widely referenced across a variety of fields. According to Csikszentmihalyi, flow is completely focused motivation.
