Hi Kent:
You're right, it only takes a time or two to experience the awful situation of not having your studff together to mae a personal commitment to avoid having that repeated.
When organized, we spend time to make time, and that is good for the students. Unprepared and disorgaized teachers usually end up wasting a lot of time, valuable time that's taken away from students. So students suffer when the teacher is unprepared.
