I certainly need to, but unfortunately I don't, at least not on my person. In the winter, I wear a lot of shirts without pockets, so I get out of the habit of carrying one, then when the weather warms up and i can break out the short sleeve shirts with pockets, I always forget to include one. I do however have plenty of pens at the office, and in my bag that travels to and from work with me, but after that, and on the weekends, I have to go for the pen stash when I need one.

I'd like to get into the habit of carrying one, and a good notebook, so it looks like I either need to reconsider where to carry them or reconsider my winter work wardrobe.
