Originally, I was not going to participate in Blog Action Day. Am I allowed to say that? And what changed my mind? What changed my mind was Lifehacker's Blog Action Day post. In particular, one tip they gave got me thinking. The tip was "Bring Your Own Utensils To Work."
Before I read the details of the tip, my mind went a completely different direction than the article. The article was talking about forks and spoons - bring the metal ones and wash them instead of tossing the plastic ones. Where my mind went: writing utensils.
Maybe I spend too much time on DIYPlanner.com, but I started thinking about at nearly any office I've worked in, you go to the office supply cabinet and you find just about the same thing: a cabinet full of the cheapest pens and legal pads you've ever seen. The pens are doing well to last a few weeks before getting lost, stop working, or just get swiped off your desk by a co-worker. The notepads aren't much better. You turn a page 3 times and it rips off.
I've been switching back and forth between a couple pens at work. I've got a couple Pilot G2 pens, and a couple inexpensive fountain pens. I like the idea that instead of just using a pen a few weeks and then tossing it when it quits working, of buying a pen that has refills available. The fountain pen (Lamy Vista, for those of you who are curious) are even better because instead of a cartridge you can get a converter. The converter lets you refill from an ink bottle. I can use the same pen for years and years and the only cost (financially and environmentally) is a bottle of ink.
The cost of a good fountain pen is more initially, but over time you've got a pen that is enjoyable to use and a lot less plastic going into the land-fill.
Along those same lines, I've been using a Circa notebook from Levenger. I also purchased the hole-punch to go with it. This means I can hole-punch just about any size and kind of paper and just toss it into my notebook. I have a pretty much infinitely refillable notebook.
