"Le Journalier" or the "Day Planner"

Ok, this one is a bit special... :)

If you constantly forget what you have to do in a day... if you constantly write every evening what you plan doing the next day and every week you write the same things !!! (Children planning... )

Then try "Le Journalier" / "Day Planner". This is a mechanical equivalent of a to-do list.

If you make any of this, be so kind to let me know... I'm really curious on the ... concept....
