The Serenity Prayer

God, grant me the serenity

to accept the things I cannot change

the courage to change the things I can

and the wisdom to know the difference.

 

This is where it stops when used at an AA meeting.  However, there is another verse:

Living one day at a time,
enjoying one moment at a time.
Accepting hardships as the pathway to peace.
Taking, as he did, the 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;
that I may be reasonably happy in this life,
and supremely happy with Him forever.

—Reinhold Niebuhr, 1892-1971
