Geoffrey, I'm in the same boat as you. Personally, I want to live a little before I ever think about opening up a gym of my own or starting a family, wife, kids, dog and cat.
I think many owners have to be sensible and I have seen it being very successful where they also hire an office manager or gym manager besides program directors to offset the workload. An owner might simply not be able to commit to coaching 25 hours a week or various levels of team. For perhaps a short time as the gym ramps up and grows, but not a long term situation. Perhaps they can commit to coaching one or two levels ( level 4 or 5/6, developmental or at the most difficult, optionals [ which in some sense, coach themselves by that point ]).
After my first few congresses, I realized that if I wanted to survive as a coach, I would need to be able to coach many things or everything. After a few more congresses and years working as a coach, I then realized that unless you are a coach in a big program and are in high demand; that only by being an owner is a decent living. Another route is to also have alternative sources of income be it a day or morning job, chiro/massage/PT.
Personally, I still have some thoughts of owning or co-owning. However, if I want to start a program and take a gymnast to level 10, it would take at least 10 years. On another note, I personally wanted to know as much about every job in the gym, before venturing on my own to doing it. That's just myself. I've made it a focus ever since then to always understand how the office works, number crunch, insurance, marketing, etc, etc. If I ever went into full bore, I'd be hitting Jeff Metzger and similar clinicians beforehand, too.
