I have always 'used' a calendar but until I found a the lovely Flylady online (she is the Good Mom voice in one's head) I used notes, multiple calenders, emails ... now, if it is not on the calendar it does not exist. On calendar, off the worry part of the mind.
The next very helpful step is knowing where the keys are - always in the same place, so when I arrive home, I put my keys on their hook and when its time to run out the door (school starts in HOW many minutes????) the keys are there.
That of course leads to gas in the tank. Fill up before you need to. Saves a lot of angst, (and if your windows are iced up make sure to give yourself extra time to get your vehicle ready to go).
Which leads to clean the car interior (get those tissues in a garbage bag, homework into the house, back packs hung up by the exit door).
This leads to the 'Launch Pad' in the next Organization post.
