This quote is from Snow Day by Billy Coffey. I first heard of him when I was reading his blog http://www.billycoffey.com/ He's one insightful man, so I was glad to see his book in my local library.
I mostly enjoyed it but felt that at times he was too didactic; trying to cram in way too many lessons learned in a short amount of time. One day actually. I'd recommend it, though. It made me think.
