How to hug a porcupine

I'm reading this book loaned to me by my friend Sue called, "How to Hug a Porcupine" by Dr. John Lewis Lund. It is soooo good! He describes so much about relationships and how we can treat each other (spouses, kids, friends..). He has a challenge to go an entire month without criticising anyone! If you mess up you have to start the clock all over again. I want to try it, but I'm afraid because I know it will be a challenge and then I think, "man, I must criticise a lot... how sad". SO the challenge is on. In the words of the author, "If criticism worked we would have changed the world long ago." I've got nothing to lose!
