writing puns/jokes and comments like "lol" next to the text. also use exclamation marks for nor reason except to stay at comically high levels of engagement while reading, higher visibility when reviewing.
for facts: if it can be placed on a map, i do that. if it can be reduced to a diagram/flowchart, i do that. arrows flying everywhere on the page. make lists of data next to the relevant paragraph so that I only look at the written words and not the printed words ( like in TN history book)
for principles: save full sentences online/ notebook. then write smth about that in order to clarify my own thoughts on it. brain dump. go back to it every few weeks/ when bored and do some assumption-storming, get clearer writing.
force my dog to listen to my rote memorization/summarizing.
