People write books for many reasons. Some write for money, while others have stories to tell. Some write to fill personal or social needs. I wrote as a result of a number of factors that seemed to coalesce at one time. The first factor was a client who didn't pay me. I thought at the time that the advice I had given was good. Since I had done the research for the opinion, why not put the information I had gleaned from various sources to good use?
