I've got to get away from learning Tai Chi from certain instructional programs. With Yoga, I have Wai Lana. I like Wai Lana. I won't say names but I'm highly annoyed by the person who teaches the instructional TV show I'm resigned to watch. He is an abomination to me. An anathema. A plague. Phage. Eviiiiiil.
I think instructional programs are really hit or miss. I've learned certain yoga asanas this way, and it really wasn't as effective as doing the practice with an instructor in real time. In many ways, I feel that wellness/exercise programs are a huge money-making scheme for lots of people. But I do hope you continue with Tai Chi, because it really is a wonderful practice that's been around for eons.
If I could find a free class, I will. As with knitting, somehow, I think that learning/participating in person might help me initially. I pick up Wai Lana really quickly but...with knitting...I had to learn in person before I could even grasp the concept. Even then, it took me three months to finally make something credible.
With Tai Chi, unless I can find something as interesting as Wai Lana, I'm going to need a coach.
