Advice for beginners:
Please stop seeing being a beginner as something negative. It's actually quite an amazing thing, going through the effort to learn something new.
In fact, being advanced is actually more dangerous, because it comes with the temptation of thinking you might know something. That's what actually can hinder or stunt continual learning.
Honestly, I love being a beginner and working with beginners. As a teacher I embrace the challenge, and as a practitioner it helps me stay close to the learning process and connect with my students.
So when I get comments like "maybe I should wait until I have a handstand to attend the workshop" I think NO! Not being able to do something is the best possible reason to take a class on it.
Are you afraid of failing? Good luck learning anything. I can guarantee you will fail, but the point is to learn lessons from those failures.
Afraid of other peoples' judgement? Don't be. Most people just worry about themselves. The fact that you're there, going through effort to try to learn something you can't do yet is a very respectable thing.
Comparing yourself to others? Quit it. I can also guarantee there will be people better than you who learn faster. If you focus on their learning process instead of your own its only a setup for disappointment.
So in conclusion, much love and respect to all the beginners out there busting their asses to learn something. Get out there and get after it.
