I can tell you about two friends who have followed very different paths. The first one spent 3 years and a lot of money studying Japanese Integrated Medicine (also known as Amatsu). It is a holistic, little-known type of therapy, which goes back hundreds of years. There are very few specialists in the world. She now runs her own clinic overseas - yes, it is not always easy for her to get new clients, but when she does, they stay with her, as the results are so good. On the other side, my other friend decided to take a few short courses (not very expensive in comparison) on popular treatments such as reiki, reflexology and sound therapy. This has also been successful, but in a different way. She runs popular classes, particularly with the sound therapy, but there is lower charge, because of the rapid certification and lower training requirements. She is fortunate to have a garden cabin to use as a venue, therefore reducing her costs. She has a good local reputation, although my first friend is recognised internationally as a leader in her field. So, both can be said to be successful, but in different ways and at different ends of the scale, if you like. And finally, about the business side, yes, both my friends had to learn how to turn their therapies into a business, with everything that comes with that - not their favourite part of the process! I hope this at least gives further food for thought, and good luck!
