I've found myself in this mode before, too. A couple of years ago I was preparing for weeklong wilderness backpacking trip with some friends. I'd recently quit my high-stress job to take some time off, and I had a few new pieces of gear I wanted to test before relying on them on a longer trip. When I looked at the calendar, though, every weekend before we were to leave was already spoken for.
I was worrying about it to my wife, trying to decide whether I'd just have to use the old worn out gear or risk it with the new stuff, when she stopped me: "why don't you just... go on Monday?" It took me a second to even get what she was saying—I was still so much in work-all-the-time-mode that my brain didn't even consider whatsoever the possibility that I could just... go off and go camping on a weekday. I was really baffled for a moment, and I've reflected on that a bit since, it's funny how you can be trapped in your own default operating mode and not even realize it.
