A few years ago I wrote my first book. "How to Keep Your Students Happy" 50 activities that English teachers can use in the classroom in order to... keep their students happy. It has been selling well and I want to thank everyone who has bought it or read it on Kindle. Every time one is sold, Amazon sends me an e-mail. I love seeing how many counties all over the world my book has been read in. It always gives me a smile.
