In my early 20's I dropped out of community college to focus on my money, long story short I'm currently 26 and head of a ~100 million dollar engineering company that I built from scratch. For a while I've been wanting to go back to school for the sake of having a degree. Engineering topics are too easy for me and I'm already extremely well studied in a wide array so, as I plan to grow my business into the billions, I'm wondering what more can business school actually teach me?
I have no formal training in business, I've only worked one job in my life at that was as a cashier at a drug-store for about 8 months when I was 19. I've had no business mentoring from anyone in my life, only from internet research. I'm extremely efficient and very good at figuring out goal oriented things, organizing processes and hierarchies to run smoothly, understanding and managing complex systems in general. Very good at recognizing peoples skills and talents, putting them to use, good at recognizing employees with advantageous personality traits, and so on.
I know little about complex business schemes. Most of my wealth basically comes from engineering complex and expensive items and selling them to people who have money. I figure I could always hire someone with a business degree but they wouldn't be "thinking for the company", as I would in my shoes.
So what exactly would I learn in business school? I currently just look at business as any other mechanical system, governed by cause and effect, and all the variables in the world that interact with it, making money is easy, I just want to be even better at it.
