Jeremy Siegel, author of the widely acclaimed "Stocks for the Long Run," was one of my professors in the MBA program at the University of Chicago. As one who started buying stocks with paper route and lawn mowing earnings while at Robinson Junior High School, I have embraced the "stay the course/live with the bounces" philosophy longer than the 25 years I have been a certified financial planner. I would not have dreamed the time would come when I would even temporarily abandon that philosophy.
