It's autumn, and autumn is my season. Part of my annual duties is to wander about, stamping the word DEATH on fallen leaves. This year, as an experiment, I spray-painted some of those leaves white. To make them stand out so they'll be easier to find when I strew them about.
The reason I do this is because autumn is the season that implicitly says MEMENTO MORI. Which is Latin for Remember to Die. There's no big hurry on this one. But it's on your list of things to do.
Because if you haven't died, you haven't lived a rich, full life yet.
