GEN: quotation?

[Deborah Smith McLeod <athanasd@BELNET.BELLEVUE.K12.WA.US>]

I can't believe I'm asking this but I really can't find it - I guess it's
not a quotation worthy of inclusion in any of my reference sources.
A teacher wants the words to that inspirational saying that begins
something like "God grant me the serenity... and the wisdom to know the
difference."

I tried any key words I knew from the quote to no avail.

TIA for your help!
