“there are three kinds of people in the world: those who don't know and don't know they don't know; those who don't know and do know they don't know; and those who know and know how much they still don't know.”
“There are those who know and those who don't know. And for every ten thousand who don't know there's only one who knows. That's the miracle of all time--the fact that these millions know so much but don't know this.”
“...Those who know don't talk and those who talk don't know.”
“Those who worship don't know, and those who know don't worship.”
“Those who know don't tell and those who tell don't know.”
“Those who don't know speak...Those who really know, don't speak!!!!”
