impulsivity.

whenever I'm reading about research on personality, there is always a personality categorized for being very 'impulsive.' these are usually artist/creators who advance our civilizations artisit endeavors through their creative and impulsive minds. so.. is true work only created through spurts of dopamine, an instant and rapid blurts of genius mind, and not through.. hard, diligent work, that of someone who will be categorized as an 'administrator'?
