Sometimes, the most mundane habits that are the most useful. So it is with note-taking. 

The note-taker spectrum is broad: There are the desultory note-takers, the doodling note-takers, the distracted note-takers, the ambivalent but obliged note-takers, the hyper-efficient note-takers, the graphomanic note-takers, and everything in between. On one end, the devoted declare themselves by their proximity to their favorite notebook; on the other, the reluctant announce their status with random dates recorded in Notes.

(Almost) regardless of where you fall on the spectrum, note-taking is an important aid to comprehension and a surprising access point to power. You don’t have to adhere to the Cornell Method to gain these benefits. Even if your style is more jot-down-a-word-and-circle-it-three times, note-taking can serve important functions.

First, note-taking breaks down a subject into its parts, allowing a more intimate approach to analysis: When we take notes, we get a lot closer to our subject.

Second, note-taking extends our distance to a subject: When we take notes, we insert ourselves between the subject and our sense of the subject. The resulting divide offers—sometimes forces—a broader perspective.

Third, while note-taking enables intimacy and distance, close comprehension and prodigious perspective-taking, its most crucial function isn’t necessarily the taking but the notes. Note-taking is the means by which we accumulate records. A repository of what we noticed stands as a material memory of the things that mattered enough, to us, at least, to be written down.

This is the case whether notes are clear or confusing. Ask any archivist: Notes are observations’ receipts, and those who collect receipts are the record-keepers upon which narrative power depends.

Consequently, taking notes and keeping notes is incredibly useful. It’s useful for everyone, but it’s especially useful for writers and narrators. Start or renew your note-taking efforts by having an always-open doc, always-available app, or always-ready notebook available in which to observe details, retain dates, and manage projects. The practice may act as an aid to productivity, but it will certainly provide past evidence for future meanings.
