ABSTRACT
Sheep ranchers know that in a large flock of sheep, jumping an obstacle is self-perpetuating; that is, if you cause the first sheep to jump an obstacle, all the sheep behind will leap the obstacle, whether it is still there or not. So runs habit in the animal kingdom, of which, alas, we are a part. We will persist in unskillful and self-defeating habits unless all our will and energies are marshaled to lead us to be aware and mindful to do the skillful thing-to liquidate the position losing money in a skillful way-and buy the probability of a promising new situation (perhaps to short the losing position we just abandoned on the long side).
