Back to basic

I've been practising yoga (Ashtanga and Hatha) since nearly 4 years now but I still feel like a beginner. The main reason is that I only practice once a week...
Switching recently to Ashtanga beginners (the class and teacher where it all started) we had Cathy Moran teaching one class. She told us about a new course she would be doing at Yoga Glasgow called "Foundation course in Ashtanga Yoga" and I was immediately hooked. The reason is that I still can't do the sun solution properly (Plank?! Pff...as if) and it's always good to go back to where you started. The course starts this Friday at 5:30pm so enough time afterwards to go for a Friday pint....yeah.
