So id like to get guidance and show off for my proudest long term feat which was a total accident.
Like I mentioned in my clock and chess method having a way to organize your info is key.
One thing that struck me as unusual is that I remember from very little from my life but I remember the key pad code to our house which I programmed based off my Bombers Club password from Majora’s Mask, a Nintendo game in the 90’s. Using it every day creates muscle memory but the distinct sound tone and pattern is what is most unique.
First I visualize the Bomber characters all lined up and creating the code. But even then it isn’t memorable. So I remember my door keypad and visualize that. Then I remember the sound of the tones and buttons being pressed while visualize the act. And that cemented the only secure number I rarely use and had retired and forgotten for about five years.
That’s my record for info. Hope this helps and can be modified with my clock and chess methods.
