Tucson, sorry about the finish on your new gun, I would be upset too.
It seems as tho your doing fine at your job. I’m sure the 8 hour shifts are tough. Physically I could not handle that.
Just set timer for 15 mins and pick a room, see how much you can get done. It’s usually a lot more than a person thinks.. it’s a good mental trick , you know timer goes off you can have a seat and spoil your dog more
