Our new Cool Friend is John Wood. He's been featured here before when Shelley wrote about Room to Read, John's WOW! Project. Now he's written a book to let others get an inkling of how it can be done or how to become part of their own world-changing effort: Leaving Microsoft to Change the World: An Entrepreneur's Odyssey to Educate the World's Children. You can read his Cool Friends interview here. And, if then you'd like to read more, you can visit his website linked above, or go to fastcompany.com. His office sent us a bunch of pictures of John in action, as you can see. Be sure to scroll to the bottom of the interview where we've posted more of them.
