"When you're convincing yourself that you're right, what you're saying to yourself is, 'I know who's in this market and who's about to come into this market. I know what they believe about what is high or what is low. Furthermore, I know each individual's capacity to act on those beliefs, and with this knowledge, I am able to determine how the actions of each of these individuals will affect price movement in it's collective form a second, a minute, an hour, a day, or a week from now.' Look at the process of convincing yourself that you're right from this perspective, it seems a bit absurd, doesn't it?"
