Two lines of thouhgt that occir to me ( a non-school owner, non-instructor )
1. Stop thinking of it as MA and think of it as a business. Step back and think of it as "I'm selling a service..what does it take to make that profitable?" Ignoring for the fact that it is MA (because it seems more MA business models don't work very well anyway

First off, are you charing too little for your service? Are you at maximum capacity and still not breaking even, then probably so. How about expenses? How much do you pay for rent on your location? Could you do equally well at a cheaper location? If your location is good, ar you taking advantge of it? How many students (of MA schools) enroll as a result of...walk-ups, web advertising, print/radio advertising, seminars, etc...etc.... If he answer is 'walk-bys' thne mayb your location is good but you need to maximize it...or maybe your location is bad and you need to move to a more public...maybe more expensive place?. I dunno, I don't own a business, but it seems like a lot of business manage to succeed and still offer quality tohappy customers so maybe the MA School business model is just wrong. Then again, many good people start business that fail, in and out of MA, so maybe not every BB who wants to open a school can actually run one in the black.
2) Give up. I don't mean gve up teaching, just give up trying to make it financially sustainable. Look at it this way. I do music as a hobby, for the most part. I've been doing it for a long time and do it very well and occasionally get called up to do it for money, and I love doing it. But the money I spend on it is never made up by the money I make from it. I just do it for the fact that I love doing it. It's a 'cost' in my life but...*shrug*, I don't mind because it's something I enjoy doing enough to do it anyway. Maybe you should give up worrying about breaking even and just consider it a hobby that costs more than it makes and enjoy it as that. (Assuming you are not relying on the income to feed your family)
Or ion short, you could try to stop thinking of it as "MA Instruction" and think of it as a business, "How do I make a busines profitable (given you may have to think outside the "MA Instruction" box...which seems to suck anyway)" or You can stop thinking about it as a business and just think of it as a hobby operating at a loss (as most do..._
