It's a day when you don't have to work, but you have a lot to do, but you don't want to make a list or a plan. So I just go with the next right thing.
It is a blissful way to have a weekend day. I usually end up getting a lot done, and I never feel like I'm working, just floating from one thing I want to do to the next thing I want to do.
The only rule is that I don't do anything I don't want to do.
So my nose said to write this down, now I think I'll go find food, then wherever my nose leads me next.
