You don’t get much time at ALL to work with it. Amplify it quickly or it’s gone. Repetition. Good ol’ Rote. Turn it into a short song. Same thing as memorizing a series of numbers long enough to get through a doorway [see doorway effect]. There’s also Roman Room technique as well.
My favorite little trick is putting thoughts in a virtual mental basket and carrying them through doorways. Odd but it keeps them present. Otherwise, I have to go back into the other room to remember. Relax, look around, try to forget that I was remembering and BOOM there it is, pops right up again.
