This may be drifting into "TMI" category, but... I like to take baths. No, I mean, not just "I bathe regularly", I mean, I take baths specifically for relaxation and to signal a break in the day (as opposed to a morning shower before work if I'm going into an office or otherwise going out).

If I "clock out" from my day job around 5:30pm or so, one of the first things I do is draw a nice hot bath, jump in the tub, and sit in there and soak in hot water and read a book, for about 45 minutes or so. A cup of coffee is optional. When I get out, I'm now in the "my time" part of the day.

I always enjoyed taking nice long, hot baths in the evening, but it used to be something I did much later in the evening, closer to bedtime. But I started moving them up to the "just after work" time very specifically because I needed some kind of act or routine or ritual to help demarcate "work" and "after work".
