This is a good list of promises one can make to self. But I'm not ready to take on any yet. So I just document it here and maybe someday when I'm ready, I'll come across it again :)

I promise myself...
To be so strong that nothing can disturb my peace of mind.
To talk health, happiness and prosperity to every person I meet.
To make all my friends feel that there is something in them.
To look on the sunny side of everything and make my 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 success of others as I am about my 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 to have a smile ready for every living creature I meet.
To give so much time to the improvement of myself that I have no time to criticise 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 myself and to proclaim this fact to the world - not in loud words, but in great deeds.
To live in the faith that the world is on my side so long as I am true to the best that is in me.
