It was adopted as the official creed of the organization in 1922. Written by Christian Larson, the creed was originally published under the title “Promise Yourself” in 1912. Optimists in California found the Optimist spirit well-expressed in the 10-line statement and pushed to have it adopted organization-wide. The wife of Los Angeles Optimist James V. Westervelt saw the item in a newspaper and clipped it for her husband. After publishing it in his club's bulletin, Westervelt and other Los Angeles Optimists encouraged other California clubs to use the creed. Soon after, the creed's popularity grew.
Promise Yourself
To be so strong that nothing can disturb your peace of mind.
To talk health, happiness and prosperity to every person you meet.
To make all your friends feel that there is something in them.
To look at the sunny side of everything and make all your optimism come true.
To think only of the best, to work only for the best, and to expect only the best.
To be just as enthusiastic about the success of others as you are about your own.
To forget the mistakes of the past and press on to the greater achievements of the future.
To wear a cheerful countenance at all times and give every living creature you meet a smile.
To give so much time to the improvement of your self that you have no time to criticize others.
To be too large for worry, too noble for anger, too strong for fear, and too happy to permit the presence of trouble.
