Stumbled upon Martha’s show last Jan 8, 2010. 
Here’s the link to the episode. http://www.marthastewart.com/show/the-martha-stewart-show/the-yoga-show
I particularly like the Yoga Dos and Don’ts.
“six things that provide success in a practice: enthusiasm, perseverance, courage, interest in seeking the truth, trust in the words of your teacher, and avoiding the company of negative people, or those that do not support your practice.”
