Believe it or not, the main reason I write finance articles for Seeking Alpha and The Motley Fool is to help formulate my own investing ideas. I find that some of my best ideas with regard to finance come from doing the research that is required to write an article designed to help other investors!
Of course, this is a mutually beneficial exercise as I only research stocks that I feel are worthy of extra consideration from investors in general. As I, hopefully, teach readers about a stock I am also very much teaching myself about the same stock. Some of my best investing ideas have come from writing articles, including Discovery Communications Inc. (DISCA) at ~$60 and Boston Beer Co. Inc. (SAM) at ~$150.
My main goal with investing is to make money, and avoid losing it, in the long-term. So, for as long as I write finance articles, be assured that I always have readers' best interests at heart, because often times the readers' interests are the very same as my own!
