I would probably say the same if you wanted to open a pet store or a sandwich shop with zero experience. Go work at one for a few years to figure it out. Then open your own.
I think this goes for a lot of job/career situations. Learn what works, but also experience the good with the bad.
I have a buddy who worked in the service industry for many years but opened up a food shop and almost a decade later it feels like they're still trying to figure things out and he can hardly ever leave the place.
