Why Systems Matter
Random notes are nearly useless. Without structure, your insights scatter—impossible to find when needed, impossible to connect.
A good note-taking system transforms fleeting thoughts into lasting knowledge.
The Major Methods
Zettelkasten (Slip Box)
Developed by German sociologist Niklas Luhmann, who used it to write 70+ books.
How it works:
- Each note contains one atomic idea
- Notes link to related notes
- Over time, a network of connected ideas emerges
Best for: Researchers, writers, anyone building long-term knowledge projects
Challenges: High initial setup, requires consistent linking discipline
Cornell Method
A structured format developed at Cornell University.
How it works:
- Page divided into three sections: cues, notes, summary
- Take notes in main section during learning
- Add cues (keywords, questions) after
- Write summary at bottom to consolidate
Best for: Students, meeting notes, lecture capture
Challenges: Less flexible for non-linear thinking
Progressive Summarization
Created by Tiago Forte, emphasizes layered highlighting.
How it works:
- Layer 1: Save interesting content
- Layer 2: Bold the best parts
- Layer 3: Highlight the bolded parts
- Layer 4: Create your own summary
Best for: Processing large amounts of content, building a "second brain"
Challenges: Can lead to over-collection without action
Finding Your System
The best system is the one you'll actually use. Consider:
Your work style: Do you think linearly or in webs?
Your tools: Digital, analog, or hybrid?
Your goals: Learning, creating, or both?
Practical Recommendations
For beginners: Start with Cornell. It's structured enough to build habits, flexible enough to adapt.
For knowledge workers: Try Progressive Summarization. It handles information overflow well.
For serious researchers: Invest in Zettelkasten. The upfront cost pays off over years.
The Meta-Lesson
Don't get lost in system optimization. The goal is to capture and connect ideas—not to build the perfect system.
Pick one approach. Use it consistently for 3 months. Then evaluate and adjust.
The best notes are the ones you take.
