A quotable gem–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.

Memorize it, Frame it, Keep seeing it every hour of the day, Dream it when you sleep.

The question’s answer wiki is an excellent source of insight and so are a few answers.
