Yesterday I did something great:
To be fair, it wasn't completely nothing. Missy and I went out and did some Ingress stuff. We did a tiny amount of holiday shopping. We went to the movies. (We saw Interstellar, which we loved.)
But really, all of it was without a plan, an agenda, a schedule. We just kind of chilled out.
This is not my usual fare. I've always got a hundred things going on: a podcast to plan, studying to do for work, writing to do on my next novel, a life coaching session to prep for or do, not to mention regular old everyday vanilla chores like house cleaning, bills to pay, etc.
Sometimes the very best thing to do is nothing in particular.
