What should I do?

I’m about to be 20 next month, and since I finished highschool that I’ve found myself at home most of the times. So my father told me to go to college. I told myself before that I wouldn’t go to college but start a carrer as an online entrepreneur. I love AI and use it everyday. Last Sunday I was with one of the best people I can have as a mentor and asked him which path I should choose to pursue, he told me to pursue the one path I find more appealing. He owns a small accounting firm and I was thinking to ask him to for free but my goal’s to GT business insight and implement AI automations into his busibusiness, by the time I leave, I hope I have enough expertise to do my own things, so what suggestions do you have for me?
