What advice would you give to someone that wants to grow a school community and also run an automation business? Should I focus on one at a time?

Well, this is pretty funny because you probably didn't just wake up one day wanting to run a school community and an automation agency. You're likely looking for a means to an end, so ask yourself what end you think running a school community and automation business would help you achieve. In my case, I make a ton of money with this stuff, so the end I see is money. But consider that a 17‑year‑old might say they want to make $100 million in 10 years—you need to clarify whether that's revenue, profit, bank account, etc. More importantly, recognize that your values and goals will shift over time; you won't want the same things in 10 years that you want today. So you have to be mature about that and accept that you're a changing organism whose goals evolve.
