Should I Use Notebooks More Often? (Cal’s Strategy) | Monday Advice

What It Covers

Cal Newport outlines his four-notebook system for analog and digital paper use, explaining that owning a notebook without a specific purpose leads to abandonment. He covers daily time block planning, long-term strategic planning on a reMarkable device, single-purpose problem-solving in pocket notebooks, and working memory extension using grid-lined composition notebooks.

Key Questions Answered

• •Time Block Planning on Paper: Use a lie-flat, double spiral-bound, near-full-page planner to assign every minute of the workday a specific task. Newport uses a Uniball Micro 0.5mm ballpoint on paper optimized for that pen. Keeping the planner physical and separate from a computer allows quick reference without entering the digital distraction ecosystem, and enables capturing late-night reminders without unlocking devices.
• •Strategic Planning on reMarkable: For multi-month projects, a reMarkable Paper Pro outperforms analog notebooks because it supports color, highlighting, and diagrams without carrying physical markers. Its e-ink technology mimics paper friction rather than emitting light like an iPad. The device's cost creates psychological commitment — plans stored there are taken more seriously and are less likely to be lost than notes in a random notebook.
• •Single-Purpose Problem Notebooks: Dedicate one pocket-sized notebook, such as Field Notes, to a single complex problem — a book concept, professional strategy, or health goal. Carry it at all times so insights captured during travel or walks accumulate over weeks. Returning repeatedly to the same notebook builds layered thinking on hard problems, a method Newport traces to his theoretical computer science training at MIT.
• •Working Memory Extension with Grid Notebooks: Use cheap, grid-lined composition notebooks not for archiving but for expanding cognitive capacity in the moment. Drawing diagrams, writing equations, and sketching graphs on paper allows the brain to process problems beyond its natural working memory limit. Newport attributes roughly half his published mathematics to this method combined with walking. The key specification: light blue grid lines that don't visually compete with black ink.
• •Grid Line Brightness Matters: When selecting grid notebooks for technical or mathematical work, grid line contrast is a functional variable, not an aesthetic one. Lines that are too dark visually merge with handwritten marks, making the page harder to read and think through. Newport recently discarded a 12-pack of legal-style grid notebooks because the lines were too prominent, demonstrating that the wrong notebook actively impairs cognitive performance.
• •Specificity Drives Notebook Use: A notebook purchased without a defined purpose, specific format requirement, and clear reason why analog outperforms digital will go unused. Each notebook type Newport uses solves a distinct problem: portability for brainstorming, lie-flat binding for daily planning, e-ink for color diagrams, and cheap grid paper for disposable in-the-moment thinking. Matching format to function is the prerequisite for any analog habit to stick.
