As far as you tube, it may be to just help people but I am sure advertising has a lot to do with it. It can be hard to make ends meet as a yoga teacher so many people get creative.[/quote]
Like lashannasmal stated, Going into yoga is defiantly not for someone looking into making cash loads but for helping people, but I do agree that being creative dose allow a person to making a modest living. Other certifications help such as becoming an Ayurvedic practioner, holistic health counselor, massage therapist ect. and can really expand your practice because you are able to discover differing views and angles. Massage therapy and physical therapy background is great for yoga teachers. Also play to your weaknesses as a teacher. I am SO thankful for the supplementary course I have taken on anatomy and hatha yoga anatomy because I knew it as a weakness and have know found it to really allow me to tap into my inner anatomy geek.
