>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.
