I don't really see much value in it at this point. Taking a break and pursuing other interests or starting a company, maybe. But academia has just never suited me. Which is a big part of why I dropped out. While I can't say I know I wouldn't enjoy it, I do know that conventional education is not something I'd consider a worthwhile investment.
I probably should've mentioned that I have been working full-time for around five years, albeit at smaller companies. I do have a side project that I am very passionate about, but I can never seem to find the time or get motivated enough to work on it, unfortunately. I very much appreciate your insight into having side projects, and will definitely put more effort into that.
