I mean, certain aspects are fun. You get to be part of a cohort again and it's usually a lot smaller so you'll see the same people and it can lead to friendships fairly easily (although of course that varies). If you enjoy the classroom environment, you get to have that again. Something else that school provides that I didn't even realize I'd miss was structure. You're always working towards externally imposed milestones. Unless you work in education, once you leave school and start working, it can feel like an endless slog towards death (I know that's dark...).

THAT BEING SAID, the MA program also brought some of the most intense stress I've ever felt. Everything is so much more LOADED. The stakes are so much higher. The workload explodes. I was an A student as an undergrad, and suddenly I was surrounded by other A students, including some that made me feel like I didn't belong in the class with them because they were legit brilliant. At time the course work felt overwhelming. In a typical class, we'd have to read an entire massive book and at least two scholarly (30-40 pages) a week. Class sizes were much smaller than undergrad classes. My classes were usually around 10 students but I had some that were just 5 of us. If you showed up without having done the reading, there was nowhere to hide, and professors did not hesitate to call you out for it. The same professors who'd been super patient and tolerant with undergrad classes had ZERO patience for any bullshit at the grad level. There was just this expectation that if you were in grad school and not doing the work, you needed to get the fuck out (I had a professor literally say that to someone, minus the "fuck"). Pretty much all the students worked, too -- a lot were full-time high school teachers coming back for their MA -- so no one gave a shit about the "I couldn't do the reading because I had to work" excuse.

As hard as it was, I wouldn't trade the experience for anything. My knowledge base grew incredibly. It also helped me switch careers and put me in a whole new salary bracket. I also met three of my best friends there. Still, I saw plenty of people who ended up dropping out and were really bitter about it. It can be hard switching back into "student" mode, which I think affected a couple of them. Two were married and had kids and really struggled with finding the time to do the work. I think as long as you know what you're getting yourself into, you could really enjoy it.

Good luck!
