Moleskine writing template (click to enlarge)
It's not a secret that I'm a dedicated Moleskine fan. In many ways, using notebooks is easier than using a computer. Of course it's easier to find stuff on a computer, so I use Post-It (tm) notes and tabs to let me flick to various sections in a notebook. Here's a vital tip: number the pages, and leave several pages for an index at the front of each notebook.
Great tabbing hack
Moleskine hacks (customizations) abound online, and I love "The Moleskine Multi-Tab Hack" and have adapted it to my own use.
I currently have tabs for This Week (I move it each week), Today (moved each day), My Web Sites (to do lists for my sites), Personal (a catch-all tab for shopping lists and such) and Free Writing (what it says - I like to keep my free writing and browse the sessions when I get bored, or need ideas.)
