I have put together a list of all the things I might want to bring. The list is overkill, most of the time I just cross some stuff off. But I always print a copy of the list and have it on the kitchen table in the morning when I'm getting ready. I check off each item (or cross it off). Every time I've discovered something I'd forgotten or would like to bring, I've added it to the list.
I know you think you thought you knew what you thought I said,
but I'm not sure you understood what you thought I meant.
