Going to Start Working on My Second Book

I remember writing a note on my Facebook profile page back in 2008 just after self-publishing my first book on finding Happiness and the Meaning of Life that I wanted to work on a second related book(with examples and personal experiences) that would undergo a traditional form of publishing. It seems like I did not have enough material and personal life experience to work on it, which could be why I have been putting it off for 5 over years now. But now that I have gathered enough ideas/material for a thick book, I recently felt like putting together a second book. So I think working on it would be a project that would keep me busy for the next few months.
