I throw all my notes out as soon as I finish writing them.

This is essentially what I always did, but instead of "as soon as I finish" replace "at some long-overdue future time". But the notion of write-only notes was largely identical, with very rare exceptions.

Hilariously, I only kept my notes so long out of poorly surfaced guilt that I was "doing it wrong", compared to some students who seemed to come out of lecture with fancy notes practically ready for prepress...

It was fun for my wife and I to go through all our college notes and laugh at everything we had to go through! Some good classes and some bad classes.

In high school we had a nice big bonfire and burned our notes at the end of the year. Making smores was probably the best use of old notes!
