Author's Notes:

Letter 69: Here.

To my most faithful student, Twilight Sparkle,

While your objective is sound in theory generally speaking you don't want to analyze it in great detail, and remember that most ponies prefer being spontanious. Especially since many ponies are not always in the mood, and a rigid schedule can create a feeling of pressure or distress which is undesired.

So rather than an itenerary you should perhaps consider an ordered checklist for your own records.

Your loving mentor,
Princess Celestia
