I remembered this prayer the other day, it's called The Serenity Prayer, I find it quite Taoist in it's sentiment. Nobody is really sure who wrote it, some credit Reinhold Niebuhr, some Friedrich Oetinger in the 18th century, still others credit the philsopher Boethius in the 6th Century.
There are various versions in existance, I've chosen a short version as I like to keep things short and fairly simple, I've found this prayer very comforting of late.
Grant me the serenity to accept the things I cannot change;
Courage to change the things I can;
And wisdom to know the difference.
