I am sure that you will get lots of different answers, but I can give you mine.
I go into the darkroom to escape into a different world. I will usually go in with the thought that I want to print some specific negative, and I may end up with a print that I like, I may not, I may move on to something else, but whatever happens, the issues from work and the rest of my life stay outside and I focus on making images. If I come out of the darkroom with a good print, that is a bonus.
I almost always come out of the darkroom in a calmer, more peaceful state of mind than when I went in. - The question "this all I got from those 3 hours?" never comes up since my goal involves not so much what I get, as what I lose.
