I am going to go on VISTA print tonight and have a banner made for my classroom that looks like this.
This is my life's mantra and I think it would serve every child well to memorize it and say it under their breath when they need it. I have always loved this quote as my mother read a ton of Milne to us as children. There are lots of others to love as well. I also highly endorse The Tao of Pooh.
I had forgotten about it until Matt Gomez reminded me. He is a maverick Kindergarten teacher who is passionate about growing children into intelligent powerhouses in their own right. He is unafraid of criticism, in fact he welcomes it as a place of learning. Go ahead, follow his blog too.
