I try to learn something new about poker every day. Sometimes I don't, and sometimes I stupidly learn something that isn't helpful, but I still try. Since poker is a game of human interaction, the two areas where there is the most to learn are "the enemy" and "thyself." Winning poker is more than winning "a hundred battles", but the art of poker boils down to a very similar root as the art of war: know people, your opponents and yourself.
