“If you do what you've always done, you'll get what you've always gotten. ”

“And now, no matter what I thought I had done or why I did it, it has become completely untrue because of what I have done since.”

“What you haven't done by thirty you're not likely to do. What you have done you'll do lots more.”

“You will never know what could have been done until you start doing what needs to be done.”

“If you do what you have always done, you will get what you have always gotten.”
