What I miss from these conversations is an emphasis on memory. I know it has a bad rap, since it's not the same as understanding. But I have the feeling that most of our work relies on things that we've done so many times, they've been memorized and do not need to be looked up again.

Have a look at Anki https://apps.ankiweb.net/, the tool that I use to make memory a choice. See also Michael Nielsen blog on this: https://augmentingcognition.com/ltm.html
