There are only a few things that you take with you everywhere. Of course, everyone needs their phone, wallet, and keys. Beyond the crucial access-granting tools of contemporary life, what you carry is a choice based on the person you are and how you want to live. Carrying a notebook isn’t an obvious choice since there isn’t a need to write down your to-do list, sketch a profile of the guy sitting across from you on the subway, or brainstorm holiday gift ideas for your boyfriend’s sister. Some of us, however, have needs that only a real paper notebook can fill.
