Here is a prayer worthy of one's attention, whether one believes in God or not:
God grant me the serenity
To accept the things I cannot change,
Courage to change the things I can,
And wisdom to know the difference.
Living one day at a time
Enjoying one moment at a time
Accepting hardships as the pathway to peace
Taking as he did this sinful world
As it is, not as I would have it,
Trusting that he will make all things right
If I surrender to his will
So that I may be reasonably
Happy in this life
And supremely happy with him
forever and ever in the next.
