One of the most valuable things I learned in a FMQ class was how to clean your machine (we were all advised to bring pipecleaners, Q-tips and sewing machine oil [the oil is used on the Q-tip to make the dust cling to it]).
The importance of comfort (pillow on your seat, partly to elevate you and partly to cushion you), and relaxation -- recommended glass of wine (preferably white), music (to help establish a rhythm).
