I've written two books. My first book, Zero to Superhero: http://www.zerotosuperhero.com http://www.zerotosuperhero.com took four years to research, test and write. It was one of the hardest things I've ever done. More than once I broke down and wept in frustration. In the end, for all I learned, it was worth it, times a thousand. My second book is Economtricks: http://goo.gl/Fd8tW http://goo.gl/Fd8tW took only a year to write. I got some things off my chest. Not as rewarding, financially or personally.
