Experts

I've been coming to the conclusion just recently that there's really no such thing as an expert.

Think about it, the only thing that is constant is change, so that must mean that whatever knowledge anyone has is always going out of date. In Taijiquan, all the people I've seen are constantly learning and developing their skills, surely the definition of expert is someone who knows everything about their field? In my chosen field of IT, change is quite rapid and constant, it can be a constant game of catch up.

I've said before that in my opinion, if you can get a very solid mastery of the basics in any field you're sorted, and you can easily build on that in the moment. One of the things I've learned from Tai Chi practice is that it's pointless to try and remember lists of moves.

Get the basics right, build on them, react from them. I don't think you can go too far wrong.
