Should I pursue a DTV visa for Thailand while planning to travel and work remotely?

Hello! I’m 4 months away from my departure. I am experiencing so many mixed emotions, but anywho! I wanted to get some validation on my plan:

I was initially going to go the soft power route and sign up with a Muai Thai gym, but I recently opened up my own private practice so now I’m considering the DTV route. Which I’m finding is more feasible, since I won’t be paying for classes. I meet all the requirements for the DTV & wanted to ask if I should just go that route instead? I still want to do muai Thai, but I could always pay for single classes when I get there because my plan is to travel to surrounding countries & I would hate being tied to classes that prevent me from traveling. What do you guys think?

Also, for those who are business owners (I’m a licensed therapist), did you write up your own letter saying you can work out of the country? Did you show any tax information? I’m curious what documents you showed.

Thank you in advance! I hope all that makes sense.
