Promise Yourself

To be 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 worthwhile in them

To look at the sunny side of everything & make your optimism come true

To think only of the best, to work only for the best, & 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 expression at all times and give a smile to every living creature you meet

To give so much time to improving yourself that you 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

To think well of yourself and to proclaim this fact to the world

not in loud words, but in great deeds

... To live in the faith that the whole world is on your side

so long as you are true to the best that is in you
