Each week, I fold a 4x6 index card in fourths. This gives 8 columns (counting front and back sides) of 1.5"x4" each. At the top of each column, I put the day of the week and date. I use the 8th one for a shopping list. I put my "to do" list on the top third, my "to e-mail" list mid third, and appointments at the bottom of each day's column. It can be folded so the current day is showing, and it's easy to turn and add reminders during the week. I keep it in my pocket or purse, so it's always
handy for jotting notes as things come up, or writing down contact information! I use a compact, fine point pen that I keep with the list. At the end of the week, I transfer anything that didn't get done to the next week's list, and file the old one for a reference. Beats lugging an agenda!
