Here’s a ‘quote’ I came up with on one of my runs one day. Someday I should turn this into a lecture.
Perhaps uttered at the end of a class period:
Stick that in your head, so that when you need it, you’ll have it.
More fully:
Stick that in your head, so that when you need it, you’ll have it — more importantly, so that when you need it you’ll know that you need it, and you’ll have it to use.
In this look-it-up society, there is a time-and-place to actually know things so that they can be used.
