I don't think any of my desires or beliefs or other mental states are external to me. Many people will occasionally feel alienated from the motives for an action - "whatever possessed me to do that?". Note, however, that some people feel alienated from the white hairs that recently appeared on their heads - "who put them there?", they might ask the mirror - but the white hairs are still theirs. Similarly, I might feel alienated from an action or a mental state because it does not fit with my visceral self - image.
Dakota tribal wisdom says that when you're on a dead horse, the best strategy is to dismount. Of course, there are other strategies. You can change riders. You can get a committee to study the dead horse. You can benchmark how other companies ride dead horses. You can declare that it's cheaper to feed a dead horse. You can harness several dead horses together. But after you've tried all these things, you're still going to have to dismount.
