"sometimes it is okay to spend a day or two not feeling highly motivated."
Absolutely! The worst trick self-help culture ever pulled was fooling people that they could be constantly happy. I am not, and noone is. And once we acknowledge this, we are ironically much more content, on average. You go ahead and have a few stagnant days, or a stagnant month. It's normal, is what it is.
"the overly talkative neighbor, Dave"
Ever since you moved into the RV, it feels like you've been living in a sitcom, and Dave is obviously the annoying neighbor character. Well done for being so adaptable. I panic if my computer doesn't boot up, or if I can't find my phone, so I feel such admiration for someone who can do the second most stressful thing in the world (ie moving), and go with the flow.
Hope your mood perks up, and if it doesn't now, you know it will later. :)
