Is extensive training necessary for a Masseur in order to be successful?
I think training of some kind is crucial.
It doesnt have to be totally formal, but like anything else, you do have to train and practice to achieve. I took a community college training course rather than an official certification course for financial reasons at the time, but I have also learned over 10 years from practice, from mentors, from reading massage sites and (believe it or not) from watching educational massage videos.
I do believe in the mantra: practice, practice, pracitice!
I always want my art and talent to improve and the only way to do that is to keep learning.
