In 2012 and 2013, as markets regained their swagger post-2008, Buffett went back to the basics. His letters shared plain old-school wisdom that most investors ignore because it doesn't sound clever enough. He warned investors about the dividend trap, why selling shares could be better than collecting payouts and why even seasoned investors (himself included) are sometimes seduced by cheap stocks that look "too good to pass up." He also explained—again—why average investors should stop trying to be experts. What Buffett essentially meant was that in investing, intelligence is overrated.
