I don't easily encourage people to become full time teachers. I usually tell them to get permission from their parents, and if the parents are okay, then it is fine.
Being a full time Art Of Living teacher is not a difficult thing. It is not about undergoing severe penance, or walking through forests, or shaving your head and eating only once a day.
Being an Art of Living teacher is a very respectable position. In fact, it is more respectable than many of the other professions that people take. Art Of Living teacher do good for the society, and for that they are definitely rewarded.
