I have just finished “The Guidebook to Happiness” and what an eye opener it was. I have read many self help books throughout my life and this one is easily the best I have had the pleasure of reading. The tips and techniques Carl sets out are easy, instantly useable and make sense. What can be more important than your own happiness. I have also used many of the tips in here with my children and finding great success. I can not recommend this book highly enough and what a great Christmas gift to give to friends, family and loved ones – a path to their own happiness.
