This has been on my mind a lot, too, but in a slightly different way, I think. There have been things that I have historically done that have been really important to me (reading fiction is a good example; and watching movies that are joyous and funny and stupid) that I just got out of the habit of doing. That's not necessarily bad, but I think there was some important nutrient I was getting from those actions that I sorely needed, and I didn't notice how much I needed it till I was super deficient.

So it's good advice. Writing it up has probably helped some people.
