Take notes when you read

This graphic nails it. Most people read a book once and forget 90% of it. But note-takers? They build a ladder back to the knowledge anytime they want.

Marketing Analysis

Retention isn’t just for readers — it’s for marketers too. Every campaign, headline, or ad test should be noted and reviewed. That’s how great marketers climb faster while others stay stuck rereading the same “book.”

Why It Works

• Writing notes triggers deeper processing (a.k.a. active learning)
• Notes create easy retrieval cues for later
• You turn insights into reusable assets
• Consistency compounds learning over time

Examples

• Amazon’s “six-pager” culture: meetings run on written memos, not slides.
• James Clear keeps a database of article ideas and experiments.
• Facebook’s early marketers logged every creative test to find winners faster.
