The Kirk Report has a good post on the 48 Laws of Power…? and how the laws might apply to traders.? While many might be questionable, some are quite good, such as:

9. Win through your actions, never through argument. (Don’t waste time convincing others on message boards how good or bad a stock is and/or telling people how smart you were because of good calls you’ve made in the past. Instead, trade the stock and make your profit. Talk will never pay your bills. Show others by demonstration, not by time wasting chatter.)
