I'm a big fan of the Magic Spreadsheet, put together by Tony Pisculli and made famous by Mur Lafferty. (Thanks Tony & Mur!)
I was in a group of authors that put one together a few months ago and my writing count soared! That sheet sort of fell apart - some folks just don't work the same way - but my productivity is definitely better when I touch it every day.
Putting up a new one now. Just ping me at firstname.lastname@example.org if you're interested in being part of it.
