great thought provoking piece. My problem has always been, I give advice that is more solid than the game I actually end up playing.
Objectivity is key in this game and that is where I believe most of us become unstuck. My plan in a cold state never seems to stand when in the throws of making important buy / sell decisions.
Human volatility is mirrored by that of the market.
Really great article though.
