Amateurs Practice Until They Get It Right; Professionals Practice Until They Can’t Get It Wrong

George W. Loomis? Percy C. Buck? Harold Craxton? Julie Andrews? Anonymous?

julie02Dear Quote Investigator: The creator of the following insightful saying was listed as unknown:

Don’t practice until you get it right. Practice until you can’t get it wrong.

While searching for background information I came across this interesting variation:

Amateurs practice till they get it right; professionals practice till they can’t get it wrong.

Could you find out more about this modern dictum?

Quote Investigator: Because this adage can be expressed in many ways it is difficult to trace. The earliest evidence located by QI was in the domain of education in 1902. A school superintendent named George W. Loomis whose talk was recorded in the “Michigan School Moderator” discussed the best way to teach students to spell properly and employed a precursor of the modern proverb. Boldface has been added to some excerpts below: 1

It must be admitted that spelling is not taught successfully; indeed, the difficulty lies in the fact that it is seldom taught at all. Spelling lessons are assigned, studied, recited, but not taught. Much of the time spent in hearing children recite—guess till they get it right—should be spent in a definite teaching process, until they can not get it wrong.

In 1922 the distinctive second half of the expression was used in an educational book titled “Swimming and Diving”: 2

This coordination of arms and legs is perhaps the most difficult as well as the most important thing about the breast stroke. After each element has been mastered separately, practice the combination on land until you cannot get it wrong.

In 1944 a full version of the adage appeared in the volume “Psychology for Musicians” by Percy C. Buck who was an organist and a prominent Professor of Music at the University of London. This popular book was reprinted several times in the succeeding decades. Buck did not take credit for the saying which was presented as an anonymous definition: 3 4

What is the real difference between a professional and an amateur? Does not your mind immediately turn to the shallow explanation of money-payments? Two definitions have been made which may help you to think deeper than that:

“An amateur can be satisfied with knowing a fact; a professional must know the reason why.”

“An amateur practises until he can do a thing right, a professional until he can’t do it wrong.”

Here are additional selected citations in chronological order.
