My promised upcoming post is being vetted by a couple of friends. While it goes through the editing process, I offer you this little maxim.
I think it is a good idea every day (when practical) to try to read something that you don't understand at all (here was today's attempt). It keeps the mind working.
Of course, some of you will remind me that I also have a regular habit of writing things that I don't understand at all. ;-)
