“Worrying about tomorrow, today? Hmmmmmm. Why?”
“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!”
“Worry about today, and tomorrow when it becomes today.”
“Today is the tomorrow I was worried about yesterday.”
“Don't lose today by worrying about tomorrow!!!”
“Today is the tomorrow we worried about yesterday.”
