That will get you into the bad habit of learning only things that reinforce your self image. This is not only a severe limitation but may be the biggest problem of all. As we can see for ourselves on L19, many weaker players like to mention that they try to play like Shuwa, or whoever. Apparently the same syndrome exists in chess.
The other problem is over-confidence in one's reasoning, especially when it comes to drawing conclusions. Weaker players tend to be much more confident than strong players. The very strongest players actually are very wishy-washy. Time and again the chess writers report (and you can see this on chess sites where kibitzers are allowed, but of course also in go on kgs) that on being shown a new position weak players say things like, "White is winning" but a strong grandmaster will say,"Maybe White has chances". A very strong grandmaster will just say, "Hmmm". Actually this paradigm (which I gather applies to other fields of endeavour) seems to work so well that I suspect it may be how pros assess the grade of players they meet for the first time.
Ebooks are wonderful things. Now that I've actually read "Chess for Zebras" (at least at the very superficial level I can as a non-chess player) I see where you are coming from with those ideas. It reminds of those old books I haven't read in years, like Gallwey's "Inner Tennis" and "The Inner Game of Music." (I think the skiing one really did help me ski better.) I hadn't thought about those ideas in a while, maybe because they were based on early notions of left-brain / right-brain differences. But whether the physiology is correct or not there is something to the idea that too much thinking can get in the way of skill acquisition. I definitely think Go is more like a sport or like music than like an academic discipline.
