Interesting...I have always used my system for remembering a grocery list. I have to run in the store and get specific items. I memorize the number of items I must get...lets say 5 items. That way I can then recall those specific items along with the usual stuff I shop for. Works for me.
My solution: White pants!!
For the last 20 years, I have worn white cotton pants every day in lieu of blue jeans or whatever. I have at least 20 pair. I write lists, notes etc on my white pants. Works like a dream.
Note: Buy Clorox
