I did this, and unfortunately your fears became reality for me. Like you said, I only had a vague idea of what I wanted to do (including traveling, starting my own company, continuing education, side projects, etc). Almost 2 years into it I ended up just barely dabbling in each. I traveled for a few months, worked on some side projects, and learned some new things, but didn't really do anything "big" or traditionally…
About accomplishment, maybe the thing you wanted out of escaping the rat race was to take a break from feeling like you constantly did have to accomplish something.

100% yes! In fact, when I first left my job, this was exactly what was foremost on my mind and I intentionally took a one-month period where I essentially vacationed and didn't "accomplish" anything. I was very proud of having escaped the rat race, and felt good about it. After that is when I started to "get back into it" and work on side projects, etc. I was still confident that taking time off was a great decision, even if I didn't come out of it with an MBA or a startup.
Unfortunately, ~20 months later, things have changed. I've gotten enough negative reactions in those 20 months, and enough rejected job applications and negative conversations with recruiters regarding my employment gap, that I really start to question (even if only subconsciously) the entire situation I put myself in by quitting. I've started to lose that confidence that I initially had, and once that confidence starts to erode, it's been really hard to get back.
