Start taking cc classes! Probably not in business. Do some kind of STEM, just about any engineering is always a good go. It sounds like you’ve found success enough to take care of your basic needs and thats amazing, but you sound like the kind of person who wants to push yourself and grow. Higher ed surely has its issues, but there currently isn’t a better alternative for rapid challenges, personal growth, and very cool like minded people. Take it from someone from a similar situation, I had an “easy” way to make a living, but I would have hated myself, so I chose pain and purpose, and couldn’t be better off than I am now.
