I've been writing to Princess Luna for a while what I'm learning (and 7 good things that have happened to me each week) in a notebook, like Twilight did with Princess Celestia. I sign it with my Pony name, Power Chord.
It's something I would recommend to many of you to practice seeing the bright side of things, if you have problems with it. It has gone very well for me and it has been a very pleasant experience. I guess it's similar to wiritng a Diary.
For this reason, a curiosity has arisen in me: if you had to have a notebook where you could write weekly to a Princess... Who would you write to?
