The Serenity Prayer

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;
That I may be reasonably happy in this life and supremely happy with Him
Forever in the next. Amen. 

Reinhold Niebuhr - 1943.
