“Life isn't about trying to be an expert in everything. It's about being an expert in one thing and offering it to the world.”
“An expert is one who knows more and more about less and less until he knows absolutely everything about nothing.”
“No one will care more about your life than you do and no one is better qualified to chart its course than you are. You are the expert.”
“There are experts in little things but there are no experts in big things. There are experts in this fact and that fact but there are no moral experts.”
“Now I'm a scientific expert; that means I know nothing about absolutely everything.”
“An expert is one who knows more and more about less and less.”
