This wouldn’t work for a whole script but I found a hack for forgetting what you were leaving one room to do: say “I’m gonna put out the trash” as you start walking through the door. You forget what you were doing but the concept of putting out the trash is working its way through the slower pipeline of becoming a series of vibrations generated by your lungs, throat, and mouth, and you will parse what you just said and remember what you are doing.

For memorizing lines? Chew a piece of gum. I've found that it takes the emphasis away from my location in my mind and places some emphasis and connection with the feeling of chewing gum. For extra points, alternate different flavors for different sets of things to memorize.

Some classical techniques for memory involve creating your own mental spaces for memorising things.

https://en.wikipedia.org/wiki/Art_of_memory

something that helps is to block out as much external stimuli as possible. for example, when memorizing a pin, i focus on the grid of numbers. for a password, i focus on my computer, or something abstract related to the service i am signing on to.

i have the benefit of traveling a lot, so my computer becomes an always available item of focus, whereas the surroundings turn into a blur because they always change

"for a password, i focus on my computer"

I'm not sure what that means. When I have a password that is completely random, but well memorized and I typically use it on a desktop or laptop keyboard, I tend to find it impossible at first to enter it on a phone, because it seems to be essentially all in muscle memory that isn't applicable to typing on the phone.

it means i ignore the room i am in. i pretend the room does not exist. there is only me and a laptop.

that way, i get the same feeling of the situation no matter where i actually am.

Ah. But for me, there is only me and the keyboard. And different kinds of keyboards may not have anything in common.

pretty much the same thing :-)

Maybe try keeping something fragrant nearby your desk or wherever you would reinforce the memories.

Then you can bring it with you when you need to remember.

people are going to start looking at me funny when i start burning incense candles every time i get money from an ATM. :-)

do it with your eyes shut?
