Great if you like to go at your own pace
I decided to purchase the course when yoga first became a part of my life. I personally spent around 4 years with this course before completion. Obviously you can do. The course helped me deepen my practice but also discover the type of teacher I am becoming. There are many instructors within the course (specifically in the Live Zooms) and learning from them helps you see there is not one way to be. Everyone does something unique and great in their way. Yoga teachers in all the different classes you can take because the course is super cost effective haha ,can help provide the community and hands on teachings you may be missing in the asana side of things. I really enjoy just being in the yoga class without any expectation if you will to progress further than what I feel like. If you tell them you are doing YTT they will acknowledge you in a special way normally and if you like a studio you can keep showing up and let them see your practice and you could have a place to start teaching:). I believe my first class teaching is going to be a donation class at a studio where I did this. As someone who likes to do their own thing I really loved this. Hope this helps if you are on fence!
