I'd tell myself not to waste the time, money or energy on college.
I'm not against it in general, but going for a compsci degree when you've already gotten software dev work is definitely a waste of time unless your employer is paying for it. I just let my dad talk me into it after getting out of a bad job. Thankfully I only wasted one semester on it and got out because I found another job.
Still, that turned out to be $4k in loans for just 6 units because I couldn't file my FAFSA in time to qualify for any grants, thanks to my fucking undiagnosed ADHD father who couldn't be bothered to file his taxes or even give me an accurate income required by the form. That was $4k I could have put into savings or invested instead.
It's a troll toll. It'll get you a software engineering job with a roman numeral in the title at a company you've actually heard of. But if you're almost done then there's no reason not to stick with it.
The early years of my career were quite a slog, having taught myself to program. I started out on freelancing websites, competing with devs from the third world who worked for pennies a day. I lucked into my first salaried job, got hired through my cousin.
I will say, having some theory knowledge does come in handy occasionally. You might never have to write your own hashtable, but being able to understand the implementation of the structures you're using helps a lot to make informed decisions about how you organize and access data, especially when you're trying to optimize for performance or memory usage.
One piece of unsolicited advice you might have heard before is to not discount the power of networking. The best written cover letter in the world can't hold a candle to knowing someone who can put in a good word. Make friends with your professors and classmates, you never know who might think to look you up one day when their company is hiring. My old boss still offers me a job occasionally, more than five years later.
