“Don't worry about what you did yesterday, he said, often, worry about what you haven't done today.”
“Today is the tommorrow you worried about yesterday.”
“Today is the tomorrow you worried about yesterday.”
“Remember, today is the tomorrow you worried about yesterday. ”
“If what you did yesterday still looks big to you, you haven't done much today.”
“Never worry about tomorrow, Charlie Brown. Tomorrow will soon be today, and before you know it, today will be yesterday! I always worry about the day after tomorrow!”
