"Zoltan Csikzentmihalyi"

Student at the Enfield Tennis Academy, most likely named after Mihaly Csikszentmihalyi (pronounced 'cheek-sent-me-high-ee'), a Hungarian psychology professor. He is best known for inventing the concept of 'flow', a state of concentration or complete absorption with the activity at hand, otherwise known as 'being in the zone'. He outlines this theory in 'Flow: The Psychology of Optimal Experience', where he opines that people are most happy when they are in a state of flow.
