A planner can tell you a lot about what you owe people. There is the reply you need to send, the deadline getting closer and the appointment you must remember. It can be harder to find anything you are simply looking forward to.
I like the idea of leaving room for that too. A favourite character, a meaningful date or a reminder of a story you want to return to.
Something you recognise immediately
There is a particular pleasure in a reference you do not have to explain. Two names together, a familiar colour, a date that would look ordinary to someone else.
A small detail can carry quite a lot when you already know the story behind it. It does not have to take over the page.
Keep a moment you want to return to
Sometimes it is a particular conversation or turning point you want to remember. A short reference can be enough to bring it back.
You can keep a favourite scene close without recording every episode. A story can stay important to you even when you have not followed every conversation about it lately.
Let the page feel personal
You might want a quiet reference, or you might want the pairing's names right at the top. The amount of space it gets is your choice.
One name card beside the notes you already keep.
Names and remembered scenes alongside your writing about the story.
Keep the practical parts easy to read. You should still be able to find tomorrow's appointment without working around the decoration.
Leave yourself something to look forward to
When you next open your page, notice whether everything on it is asking you to do something. Perhaps there is room for something you chose simply because you enjoy it.
It can stay one small part of the page. It does not have to become another project.
