I went into Spring Break intending to get a lot of stuff done. I'd been building a backlog of things I wanted to do and I wanted to clear as much of it out as possible.
And I did get a lot done. Not as much as I intended, but I intended to do a LOT.
But I also left the spring break thinking about maybe trying out xkcd's 28-Hour Day at some point over the summer.
With my tendency to stay up later at night than I ever thought I would, it might turn out to synch up with my internal body clock better than following the earth's rotational cycle.
(For just one week, of course. Not for a long period of time.)
