Massage therapy is a great field! I have been in for 3 years, and having strong expectations about what I want from my career has really helped me. First off, I would recommend taking more schooling than your state requires, taking more classes, CE classes, or getting a college degree with medical influence will help you stand out from other therapists in the area. It also shows that you are wiling to learn and that you have a passion for this career choice.
You should also decide where you want to work, how much will you charge, will you rent, or be commission or hourly? Every spa and salon is different, some will pay you hourly plus commission for services you give. Some will only pay you hourly OR commission, not both. Some places will hire you as an employee, others as an independent contractor.
You will need to decide how many massages you need to perform weekly to pay your bills, but not harm your body. For example, I consider 15-25 massages a week to be full time for me, this includes spa services (mud wraps, scrubs, etc) and facials. I get paid hourly plus commission plus tip. I usually schedule my appts 30-60 min apart to allow my body to relax, I try not to work hour on the hour (repetitive stress movements wear down the body!)
For another example, some massage franchises will ask you to perform 25-35 massages a week at an hourly plus tip rate, (generally $12-$17 hourly) Your appts will usually be hour on the hour, or 15 min apart.
There is a lot to consider with massage, so I hope this helps a little bit! You can research this more at www.abmp.com or www.ncbtmb.com Good luck and please feel free to send me a message with any other questions!
