I’ve been going to yoga class twice a week every single week, for the past 3 years…I see new faces every class, some people go frequent but no where NEAR as much or as long as me. Am I supposed to have moved on by now? Why is there no one else like this in such a large class? Am I doing too much yoga?
In fact you are doing less 
and others are not doing at all.
I have been observing this pattern for many years. 90 % people join yoga (and other fitness regimen) just for the sake of it. That is why people are suffering more and more and they don’t know what to do and whatever they do, they do nothing.
Yoga should be practiced every day if you are not engaged into any other physical activity.
