Ugh... another short mediocre introduction. Repeats the origin myth.

Seems to take a very Ahrens' based framing, but screws up a few pieces. More focus on "hub notes" and completely misses the idea of an index somehow?!?

The last section of 2+ minutes really goes off the rails and recommends converting notes from other places and muddles about "Favorite problems" (ostensibly a reference to Feynman's 12 Favorite Problems, but isn't direct about it?).

Also encourages the "Feynman technique"...
