Am I doing the right thing

Dad never completed HS and my mom got cancer when I was 10. I'm 22 now and work in a trade but it just feels like it's not enough. I was never taught anything about college so I never went after high school. I wasn't really taught by my parents and kind of figured stuff out on my own. My boss plans on retiring and has planned on leaving the company to me. The only thing is that it just doesn't feel satisfying enough for me. Not only that but I haven't been taught and don't know anything about having a business. I kinda just want to move and find someplace I could work my way up in. I'd go to college if needed but I just want to know if I would be making the right choice on leaving.
