To do two things at once is to do neither.
~ Publilius Syrus, in Moral Sayings (1st Century B. C.)
What has been is what will be,
and what has been done is what will be done,
and there is nothing new under the sun.
~ Ecclesiastes 1:9, Holy Bible, New International Version (NIV)
Quotation from Publilius Syrus is taken from Oxymoronica: Paradoxical Wit and Wisdom from History’s Greatest Wordsmiths, by Dr. Mardy Grothe.
