Finally, you can undercut ruminations by taking advantage of their very nature. Their nature is to circle around in your mind, so that you will not forget them, so that you will act on them. When adversity strikes, schedule some time—later—for thinking things over … say, this evening at six P.M. Now, when something disturbing happens and you find the thoughts hard to stop, you can say to yourself, “Stop. I’ll think this over later … at [such and such a time].”
