Use “Memory Palace”!! I use “MP” in my office work everyday. And my my work requires me to memorize thousands of info. In my work,I have to access 100+ different information everyday that I have put in my MP. There are around 1200 work related rules that I have put in different MPs(around 56 MP) so far for long term retention,and I add new info to my MPs every week…It is an ongoing and never ending process!
I also use “MP” for understanding articles,new rules,issues,meeting stuffs in my work on the fly. Memory Palace is a life saver for me;and with it,I can beat anyone,handle and resolve any issue in my work! Very FAST!!!
I also use “zettelkasten” method of note taking,as my work requires me to learn a lot of terms,ideas,rules. Some of them are quite complex and interconnected. And zettelkasten method helps me a lot in this regard!
