“You can’t be right by doing wrong; you can’t be wrong by doing right” is an adage of Thomas S. Monson,  the 16th President of The Church of Jesus Christ of Latter-day Saints. Monson included the saying in his book Favorite Quotations from the Collection of Thomas S. Monson (1985). Ulisses Soares, a general authority of The Church of Jesus Christ of Latter-day Saints, used and popularized Monson’s saying at the 182nd Annual General Conference in March 2012.
     
“You can’t be right by doing wrong, and you can’t be wrong by doing right” is a saying that has been printed on many posters. Some posters credit Monson, but one poster says “quoted by Ulisses Soares.”

May I provide a simple formula by which you can measure the choices which confront you. It’s easy to remember: “You can’t be right by doing wrong; you can’t be wrong by doing right.” Your personal conscience always warns you as a friend before it punishes you as a judge.

May I provide a simple formula by which you can measure the choices which confront you. It’s easy to remember, sometimes difficult to apply: You can’t be right by doing wrong; you can’t be wrong by doing right. Your personal conscience always warns you as a friend before it punishes you as a judge.

Elder Ulisses Soares
To enhance our spirit it is required that we let bitterness be put away
Do my actions place me in the Lord’s or in the enemy’s territory?
We need to keep ourselves strong against the fiery darts of the adversary
You can’t be right by doing wrong, you can’t be wrong, by doing right

Abide in the Lord’s Territory!
BY ELDER ULISSES SOARES
Of the Seventy
President Thomas S. Monson once said: “May I provide a simple formula by which you can measure the choices which confront you. It’s easy to remember: ‘You can’t be right by doing wrong; you can’t be wrong by doing right’” (“Pathways to Perfection,” Liahona, July 2002, 112; Ensign, May 2002, 100). President Monson’s formula is simple and direct. It works the same way as the Liahona given to Lehi did. If we exercise faith and are diligent in obeying the Lord’s commandments, we will easily find the correct direction to follow, especially when we face our day-to-day choices.

So this quote is taken from the talk, “Abide in the Lord’s Territory”, by Ulisses Soares.
 
My most memorable quote was actually quoted by President Monson.  It was just too good to not use as the quote for this talk.
