> I've started keeping a short length of paracord on my desk to practice knots during video calls. It makes a great fidget toy.

This is literally what I started doing like 6 months ago, and I went from knowing only how to tie my shoes to having a great repertoire of knots. It’s great to have a couple hanks of paracord in the car now to tie stuff down, and more versatile (and safer) than the bungee straps.
