“If you keep thinking about tomorrow you will never be able to enjoy today.”
“Why think about tomorrow today, when you don’t even know if there will be a tomorrow, or if there is, if you’ll be there tomorrow?”
“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!”
“Life's too short to worry about the little things. Enjoy what you have today, not what you might get tomorrow”
“Are you thinking about tomorrow? There really is no tomorrow – not today. Everything exists within the right now and if there is a tomorrow, then that will be right now.”
“You can't have a better tomorrow, if you keep thinking about yesterday.”
