I always thought the memory palace was just bullshit for Sherlock Holmes.
I actually mentioned it because, combined with other things, it works for me.
I can actually still picture the 3 eggs in my head that this person needed, in a triangle in the fridge. Extremely easily. In my mind it’s even kinda dark in there as an extra detail. Not pitch black, but dark.
I use other things too when I’m cooking (hence the fingers at the end of the comment) because I’m busy, but that kind of visualization works for many people.
