"As we work, we use the form as a guide. It is something we work with, not something you learn to show off.
The form is a process that serves you, not an adornment you bring back to hang on your wall."

-- Chungliang Al Huang

Yoga guide.

Know your shit!
Read, watch, try, re-evaluate, PRACTICE. 
Have the confidence to take the space and time you need, to question and experiment with what you are told and to hold back if you feel something is not quiet right for you.
