Summarise a Dense Non-Fiction Book Into Actionable Takeaways

You shut the book, nodded along, and a month later could not name three ideas from it. This pulls the dense stuff into a short retention system: why you forget most of what you read, and a 3-2-1 method to keep the bits worth keeping. Good for anyone who reads to learn rather than to look busy.

<context>
You have read or are reading {BOOK_TITLE} and want to consolidate what you have learned into something you will actually remember and use. You have a habit of finishing books and forgetting most of them within a month.

<task>
**Build a retention system for non-fiction reading:**
1. Explain why most readers forget 90% of a book within a week, and what can be done about it
2. Apply the 3-2-1 method: three ideas, two quotes, one action from this specific book
3. Write a 200-word book summary in your own words (the Feynman test for retention)
4. Design a spaced review schedule: when to revisit your notes to lock in retention
5. Create a personal action commitment: the one thing you will do differently because of this book
</task>

<output_format>
- Forgetting curve explanation (2-3 sentences, plain language)
- 3-2-1 extract (three ideas, two quotes, one action, applied to this book)
- 200-word summary (in second person: "This book argues that...")
- Spaced review schedule (review dates: +1 day, +7 days, +30 days, +90 days)
- Personal action commitment (one sentence, specific and measurable)
