I recently finished off one of my little squared Moleskine buddies. I don't number the pages, but I do date every entry. This book was with me from about 30-Mar-04 to 21-April-05. Plenty of pauses for no-entries, but it was with me during significant times.
There are entries on the letter Cara sent me that knocked me off-kilter, our trip to Toronto, drawings, details on job interviews, quotes, notes on my NaNoWriMo novel, my mother-in-law's final illness and death, various journal entries, booknotes, Liz's health crisis from earlier this year, my ongoing job-search efforts, and various lists, plans, and muslings (a new word I just invented blending "musings" and "noodling," with elements of "doodling" not to be denied).
After I'm done with a journal, I write up a date-based index on the last few blank pages, with brief indications of what I wrote about that day. Post-Its hold the overflow when I run out of pages. It's a terribly linear way of recording my life and thoughts, I suppose, but I like the juxtaposition of a visual journal entry next to my wailing about "will I ever find a job?" next to my mini-comic ideas.
So the next few blog entries will be me dumping various entries I deem blogworthy from my recently retired Moleskine.
