Query: Who'd ever thought

This was a great book. Sometimes you get caught up in the hype that is presented in day-to-day media and lose sight of what is important when investing. After reading this book I changed the course of my investing from a "trader" mentality to an "investor" mentality. The best part now is that I spend about 1/4 as much time now on investments than I used to... I sleep better too!
