Flow may be the biggest neurochemical cocktail of all. The state appears to blend all six of the brain’s major pleasure chemicals and may be one of the few times you get all six at once. This potent mix explains why people describe flow as their “favorite experience,” while psychologists refer to it as “the source code of intrinsic motivation.

Nothing’s too gnarly.
