I am doing Equine Assisted Therapy. I will have four years of my under grad then two years to get my MSW. After that I will work under another LCSW for awhile before being able to go into private practice.
If you want to make money, you're going to need to go to school or at the very least become a working student with some big names and make a name for yourself .
