In order to make up for my lack of degree, I really busted my butt learning everything I needed to know to build web applications, how to make them scale, build and manage databases and mange servers. After 13 years, I haven't gone back. I'm still learning. Every day.
Going to college, you get an education. You learn how to learn. Afterwards, you start learning for real.
Granted, you're in a good place having tuition covered. I didn't. I walked away with student loans that I've since paid off. In college, you'll form friendships that last a lifetime. That's important. It's an experience worth living. You'll be lucky if the people you work with at your first job will remember who you are in 10 years (1 or 2 of them will). You'll have other opportunities later.
Leaving college early to get a job, I'd do it again. I wouldn't do it right out of high school.
