There’s a couple of things you need to be sucessful in business no matter what your business is.
For martial arts, well, you need a curriculum obviously.
With the curriculum, get a business model. what kind of club do you want? marketing?
With your model start building the business with marketing to the right demograph.
Are you ok with some bread and butter gym facility memberships? Work it in to your model.
Is your demograph workable with what you are ofering? IE: Seniors will warm to Chi Kung and Tai Chi but are unlikely to see the use of themselves commiting to Hard Core Fighting arts, Hevy sparring etc, at least the greater body of them.
Your curriculum must be designed to fit who you are teaching. Your model must fit your ability to deliver the curriculum and you generally have to keep an eye on the opportunities for promotion and further reach into the public knowledge of your school.
it adds up to a few blocks, but it is not rocket science to run a business. Unless your business is rocket science of course.
Good luck, it’s a hard grind.
peace
p.s -keeping things in perspective is always good too.
