It’s hard to say what you’d enjoy as a major or career because you don’t really give any insight into that! You say that you’re more “economics and business wired” than some friends but that you also don’t want to go into business. Your (impressive) experience setting up a business does beg the question to me on why not - there are lots of concentrations within business to consider and it seems to me to be a somewhat softer and more well rounded avenue that can be hireable. But I’ll take you at your word on that.
Lots of general avenues beg questions here - do you prefer harder and more black/white numbers? Or more that you want to help people? But obviously what you need to consider is - what do you like? What high school classes have been most interesting to you? I’ve always told my kids and mentees that whatever you choose to do, if you work hard and make yourself indispensable - you can usually go far.
