Psychologists describe flow as “autotelic,” from the Greek auto (self) and telos (goal). When something is autotelic—i.e., produces the flow high—it is its own reward. No one has to drag a surfer out of bed for overhead tubes. No one has to motivate a snowboarder on a powder day. These activities are intrinsically motivating, autotelic experiences done for their own sake. The high to end all highs.
