Flow state

That mode where the activity carries you, time disappears, and you stop thinking about yourself. It only shows up when the task is hard enough to demand you and easy enough not to break you.

Definition

A subjective state of complete absorption in an activity, characterised by deep focus, loss of self consciousness, distorted sense of time, and intrinsic reward, occurring when challenge and skill are well matched.
