[Having recently had the very unexpected opportunity to get my hands on an accomplished person it was a real eye opener. Like being back at the beginning ( actually had a white belt on too - which was very apt
) and getting your mind round something like this. For those who have an open mind to learning it is one of the best feelings - one that I want to repeat again in the not too distant future.
Exactly why I recommended in another thread that people go see someone with a world-acknowledged level of accomplishment in order to get a feel for what the "Real Stuff" feels like. That's what I did as soon as China opened its doors and it gave me the ability to avoid a lot of time-wasting later on.
Notice that I said "feel" (well, and see, of course)... the development and usage of the body and movement is quite different in real experts. The reason I say "feel" is that while they're generally very friendly, etc., they seldom reveal much information. I was just talking to a friend of mine about a bunch of Americans that have been following one reasonably knowledgeable teacher in California for 20 years and they're basically about where they were 20 years ago, although they know a number of nice-looking forms now.
