I know we have a few listed above in one of the stickies, but I'd love to add to it. While reading a bit of Spiritual Midwifery today, I came across this gem:
"Keep your sense of humor - it's a priceless gem which keeps you remembering where it's at. If you can't be a hero, you can at least be funny while being a chicken." Ina May Gaskin.
Anyone else have any to add?
