“Never put off till tomorrow what you can do today” is a proverb that might be a thousand years old. The proverb has had many parodies. “Always put off until tomorrow what you can avoid today” has been cited in print since at least 1913.
 
“Never put off for tomorrow what you can avoid altogether” has been cited in print since at least 1964, when it was printed in Howard Kandel’s book, The Power of Positive Pessimism: Proverbs for Our Times. The syndicated columnist Ann Landers wrote in 1994, “Gem of the Day: Never put off until tomorrow what can be avoided altogether.”
