Not the person you asked, but I've learned that if you're not careful about what you tell your employers and/or coworkers that it will almost invariably come back to haunt you in the form of unpaid labor.

It took me an embarrassingly long time to realize that (my 30's), and now I keep my conversations with my coworkers very utilitarian and divulge minimal information about myself. I try not to be a dick or anything, I'm polite enough, but pretty much everything I talk about is either directly relevant to work and/or so surface level as to border on "vapid".

ETA:

Just as an example, I used to have really bad sleep issues in my 20's that would make it so I wouldn't be able to get to sleep until around 4am, if at all. I made the mistake of bringing that up at work to my manager. Two weeks later I got a phone call at 3am because there was something he wanted to look at and "he knew I would be up". I was up, but I didn't really have much desire to get my laptop out and do work. I liked that job at the time and I liked my manager, so I did it anyway, and it wasn't until years later did I think about that incident and how utterly weird it was that I was sort of being punished for my insomnia.

My sleep issues have gotten a lot better now, so if someone calls me at 3am I probably won't hear it because I'll be asleep, but I remember that incident now and have it constantly spinning in my brain when I chat with coworkers.
