Re: Learning from other arts?
You gave a few examples which to me seem to suggest that a short side step outside the art will help you progress. This would only work when you already know what is missing, or your level of comprehension is sufficient enough to understand the 'other' perspective. I think it would have been a mere matter of time before you would have figured it out yourself. The visit to the other art was only a catalyst. I agree that probably does not have much impact on your technique. Philosophically speaking you could make bigger leaps though.
