God grant me the serenity to accept the things I cannot change, courage to change the things I can, and the wisdom to know the difference, living one day at a time; enjoying one moment at a time; taking this world as it is and not as I would have it; trusting that You will make all things right if I surrender to Your will; so that I may be reasonably happy in this life and supremely happy with You forever in the next. Amen.
