IMHO, the Serenity Prayer is the single greatest non-denominational prayer ever written. It comes from a longer prayer written by theologian Reinhold Niebuhr. For the 3 of you living under a rock, it goes like this:
G-d, grant me:
The Courage to change the things I can,
The Serenity to accept the things I cannot change, and
The Wisdom to know the difference.
There are also some swell parodies:
“God grant me the Senility to forget the people I never liked anyway,
The Good Fortune to run into the ones I do,
And the Eyesight to tell the difference.”
"Grant me the Serenity to accept the things I cannot change,
the Courage to change the things I cannot accept, and
the Wisdom to hide the bodies of those people I had to kill today because they pissed me off.
And also, help me to be careful of the toes I step on today
as they be connected to the ass that I may have to kiss tomorrow.
Help me to always give 100% at work
12% on Monday.
23% on Tuesday.
40% on Wednesday.
20% on Thursday.
5% on Friday.
And help me to remember...
When I'm having a really bad day,
and it seems that people are trying to piss me off,
that it takes 42 muscles to frown and only 4...
to extend my middle finger and tell them to bite me!
A Librarian's Serenity Prayer
Lord grant me:
the Serenity to accept that not everything can be found on the Internet...
the Courage to go to the Library
and the Wisdom to evaluate the information I do find.
A Wikipedia Serenity Prayer
Grant me the Serenity to accept the pages I cannot edit,
The Courage to edit the pages I can,
And the Wisdom to whack the hell out of any troll who gets in my way.
A Screenwriters Serenity Prayer
“God, grant me the Serenity to accept the nominations I cannot change,
the Courage to watch the broadcast without hurling sharp objects at my television, and
the Wisdom to know the difference between the opinions of the stodgy Academy members and my own.”
A Synagogue/Church Goer's Serenity Prayer
Grant me the Serenity to accept the liturgical norms I cannot change,
the Courage to correct the abuses I can change, and
the Wisdom to know the difference
Now we hug.
There. Much better. Anyone for coffee?"
