When I teach arts administration in college classrooms, my students will tell you that in almost every class I say "don't start a theater company."
Now, in class, I usually add non-profit to the sentence. Running a non-profit requires paperwork and boards and layers of administration that are worth it if the company is strong, but will hold you back when you're just starting out.
Theater company can be changed to any organized performing arts collective. I don't mean don't collaborate. Far from it. What I do mean is that by staying nimble you may be in a better position to adjust when needed, mix it up, and find your path with knowledge based experience.
