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.

If you find the 'God' word a problem, replace it with 'Universe' or whatever means something to you. Robbie Williams used to replace it with 'Elvis' when on tour. The depth of wisdom is this simple prayer cannot be underestimated. It can change your life.
