"The Turtle Mind: 1. Think in terms of the long run when trading. 2. Avoid outcome bias. 3. Believe in the effects of trading with positive expectation. The Turtle Way views losses in the same manner: They are the cost of doing business rather than an indication of a trading error or a bad decision. To approach losses in this way, we had to know that the method by which the losses were incurred would pay out over the long run. The Turtles believed in the long-term success of trading with positive expectation. In fact, we were taught that periods of losses usually precede periods of good trading."
