Never Split the Difference

Scenario Exercise

Your landlord wants to raise rent 20%. Using the "mirroring" technique, what would be your best opening response?

A "That's way too much. I'll move out."
B "A 20% increase?"
C "Let me think about it and get back to you."
D "I'd like to counter with a 5% increase."
Mirroring is repeating the last few critical words someone said. "A 20% increase?" forces the other party to elaborate and often backpedal — without you making any demands or concessions.

The Ebbinghaus Forgetting Curve is brutal. Passive reading creates an illusion of learning. Active recall — testing yourself — is what builds lasting knowledge.

How It Works

Three steps to
actually remembering.

Pick a book, drill the concepts, watch your retention soar.

01

Pick a book

Search our library of business and self-help bestsellers, or upload your own PDF/EPUB. We generate exercises from the key frameworks and ideas.

02

Drill the concepts

Work through quizzes, real-world scenarios, fill-in-the-blanks, and flashcards — all generated from the book's core teachings. Takes 10-15 minutes per session.

03

Retain for life

Our spaced repetition system brings back concepts right before you'd forget them. After 4 sessions, the knowledge is locked in.

Exercise Types

Not just quizzes.
Real understanding.

Different exercise types target different types of retention.

📝

Concept Quizzes

Multiple-choice questions that test whether you understand the key frameworks, not just recall facts.

🎯

Scenario Exercises

"Your boss just rejected your proposal. Using technique X, how would you respond?" Apply concepts to realistic situations.

🔄

Spaced Flashcards

Key terms and frameworks on auto-rotating cards. Delivered at scientifically optimal intervals for maximum retention.

✍️

Fill-in-the-Framework

"I've read 'Thinking Fast and Slow' twice and still couldn't explain System 1 vs System 2 to someone. After 3 BookDrills sessions, I was using the concepts in meetings."
