I completely agree. The hardest people to compete against are those who see what works and what doesn't and change their strategies accordingly on a regular basis -- a self correcting missile to a target. You need to orient your ego away from just being about your ideas or specific strategy to instead being a master executor whose goal is to win. It is even worse to compete against people who also study your strategy with an open mind and then incorporate the best elements of your strategy into theirs. Then it becomes a game of resources, connections, marketing and focus, rather than just a competition of ideas.
