An idea that might be foreign to people who write in text editors.

You can use an outliner to write multiple documents.

Try creating a headline called My Diary.

Then every day, add a subhead with the day's date.

Do it for a few days until the strangeness wears off.

Does this make sense?

Here's a screen shot of my "worknotes" diary, which is one level deeper.

You can think of every major head under a day as a separate document.

In fact the CMS sees it that way. So I have one document which in turn contains many documents. Actually thousands!

For many people this will be a new way of thinking about writing.
