There are a few good Tai Chi folks that I follow and enjoy their friendship on Facebook and elsewhere.
David Gaffney is one. He has co-authored some outstanding books on Chen Taiji. He also posts insightful articles on his blog.
The latest is very important to all of us. It's frustrating for all teachers when their students want to practice in an intense way before they have paid their dues on good structure and body mechanics. I guess a lot of us Westerners are guilty of trying to rush things along.
I encourage you to read David's post on "competency before intensity."
