I've been doing the sentence stem work in Six Pillars and have found it to be pretty useful. One side-effect is that the further I go with this work the more distant I feel from most of the people I deal with in daily life; I wonder where that's going to lead? But even without the stem-completion work there's much useful matter in the book. That's interesting. I'm curious, why does this sentence stem work keep you away from people? I didn't done this practice though. I've noticed that practicing these pillars improved my relationships. If you're interested in subconsciousness, there's a quite popular book "Blink". Despite it consists mainly of tales, you can get some useful information from it. Most people don't even realize how huge part subconscious thinking takes in their lives. It's a good thing to stay in touch with it, to know what influences your behavior. I think that if you abandon stem completion, you would just limit your awareness [can somebody tell me if I've used a proper conditional here, does it sound right?]. That's what I think.
