“When you think you know everything, it means that you actually know nothing.”
“If you think you know everything; you know nothing. If you think you know nothing; you know something.”
“Just because you don't know everything don't mean you know nothing.”
“As long as one remains curious, one makes progress; it is when you think you know everything that you are actually out of date.”
“Most everything you think you know about me is nothing more than memories.”
“Just when you think you know everything you can about a person... surprise!”
