Plans and choices to make after military service

Hey,

So after completing my military service in december, I've been on the fence about what to do next. I'm very interested in economics and business, but can't decide whether I should go to college, or just start a business. In Finland college is free, but I feel like it's going to cost me 5 years . 5 years that could be better spent growing a business, networking, and learning lots and lots of stuff I couldn't learn in college. I would really appreciate it if you guys shared your opinions and experiences.
