Aim

Maximise the intake of information and miminise the time invested in low-quality sources.

Process

Make two passes through the book:

1. Read the book, marking all the passages containing valuable information.
   • Do this swiftly, without actually rushing.
2. Go back through the marked sections, and digest them thoroughly. Use whatever methods seem most suitable:
   • Zettelkasten
   • mind-maps
   • bullet-points

4 types of text sections

1. Useful and difficult to understand.
2. Useful and easy to understand.
3. Not useful, but hard to understand.
4. Not useful, and easy to understand.

Type 3 are unprofitable time-sucks. Use them to sharpen your ability to identify the usefulness of whatever you're reading.

Processing notes

• Go back to primary sources, where feasible.
• Refer back to existing Zettels and other references, seeking out deeper connections and patterns.
• Come up with your own mental models and interpretations.
