I have been using post-it notes and a pen on my desk lately and it feels like virtual ram for my brain. Instead of holding X variables in my head I can hold X+5 or whatever fits on the post-it note. The ephemeral nature and small footprint makes it easy to scratch out brain-exstension-only notes without being tempted to start making a reference document like I would in a notebook. The note is extremely valuable to me for its lifetime, and a day later I'll glance at it, say "I have no idea what this means," and toss it.
