Is owning a studio worth it? Please give me your top tips for opening. Do you think is just a trend?

I always wanted to have my own studio, at this point I mostly only hold privates, semi privates on reformer, they are all by referal. When I still worked at the studios my classes were usually full, with a lot of regulars. I've been teaching full time for 2 years and thinking of bigger studio for longer. I am almost fully stott certified (I need to take barrels and ACCB course) and I also invest plenty into different workshops.
Then I am mad at myself for investing so much into my education to be holding classes at one small room with limited capacity where I basically cannot add equipment, not making that much money and then there are instructors who did one certificate and opened a studio half a year later and their business is thriving now. My clients and friends and family are super encouraging for me to open a bigger place but we live in a rather small town, I don't think a small town can hold another studio and I don't know how I will put myself out there on social media to attract new clients. I know studio like I want is a huge investment and risk. I'd really like to have 4 reformers with towers, 4 chairs and mat & barre classes, if I'd be lucky enough I'd find someone to hold ballet class for adults once a week.... I come from business owner family, and I worked in it untill recently so I know the advantages and disadvantages of it.
