“Do what you haven't done is the key, I think.”
“What you haven't done by thirty you're not likely to do. What you have done you'll do lots more.”
“Don't live to be judged for what you haven't done. Live to be judged for what you have done.”
“If you ask people what they've always wanted to do, most people haven't done it. That breaks my heart.”
“Things don't always turn out the way we plan, but don't ever let what you haven't done eclipse all the good you have done and are doing.”
“If what you have done yesterday still looks big to you, you haven't done much today.”
