I thought of this one day and it did seem a tad depressing, but on the other hand...
I did well in school, but I could never just mentally relax. After being at school all day, there was always something I was supposed to still be doing...homework, studying, etc. my time at home was never fully "me time," as there was always more work I was supposed to be doing at home.
Now that I work full time, when I get home, there's nothing I'm obligated to do. I physically cannot take work home from my job and I'm very happy that it works that way. I can completely and fully relax and forget about work at the end of the day. There's no homework or studying that I'm supposed to be doing. Plus, I make money now as opposed to when I was in school and so I can buy whatever the fuck I want.
I realize that not everyone has a job like that. My brother has a WFH job and seems like he works 24/7. But I'm thankful that I have an entirely separate work life...I'm either on the clock physically at work or I'm not. And I have a much more satisfactory work life balance than I did when I was in school.
