It would depend on your talent, your skills and your incliniation. What would you like to be doing 5 or 10 years from now? If money is the only reason you will be entering any career then it's not worth it. Seek what would really take you off your feet and fall in love with the field itself. Do your homework first and read about books regarding massage/spa therapy.
There is two books that I can suggest:
The Massage Therapy Career Guide by S. Capellini
The Spa, Massage Therapy and Wellness Resource Book and Career Guide by E. Estipona
You can also visit the blog www.yunesa.blogspot.com
Both are available on Amazon.
Hope this helps.
