Ultralearning receives mixed reviews, with an average rating of 3.95/5. Positive reviewers praise its structured approach to self-directed learning and practical principles. Critics find it repetitive, overly long, and lacking novelty. Many appreciate the author's personal experiences and case studies, but some feel the examples are limited. Readers value the book's insights on meta-learning, focus, and directness in skill acquisition. While some find it inspiring, others argue it could have been more concise and question its applicability for average learners.

Ultralearning: A strategy for acquiring skills and knowledge that is both self-directed and intense.
Self-directed learning. Ultralearning is a powerful approach to rapidly acquire new skills and knowledge. It's characterized by:
Intense focus and dedication
Self-directed study methods
Ambitious learning goals
Unlike traditional education, ultralearning empowers individuals to take control of their learning journey. This approach has been used by numerous successful individuals across various fields to achieve remarkable results in short periods.
Real-world examples. The book presents several inspiring case studies:
Benny Lewis: Learned to speak new languages fluently in three months
Eric Barone: Taught himself game development and created the hit game Stardew Valley
Roger Craig: Used data analysis to dominate on Jeopardy!
These examples demonstrate the potential of ultralearning to transform one's skills and career trajectory.
Metalearning means learning about learning.
Research and planning. Before diving into a new subject, invest time in understanding how to learn it effectively:
Research the subject's structure and common learning approaches
Identify key resources and learning materials
Break down the skill into concepts, facts, and procedures
The Expert Interview Method. One powerful metalearning technique is to interview experts in the field you're studying. This can provide valuable insights into:
The most effective learning strategies
Common pitfalls to avoid
Essential resources and techniques
Aim to spend about 10% of your total expected learning time on this initial research phase. This investment will pay off by making your subsequent learning more efficient and effective.
Focus doesn't need to be exclusive to the domain of those who have endless hours and large swaths of free time on their schedule.
Combat distractions. Develop strategies to maintain focus:
Create a distraction-free environment
Use techniques like the Pomodoro method (25 minutes of focus followed by a 5-minute break)
Practice mindfulness to improve concentration
Optimize arousal levels. Different tasks require different levels of mental arousal:
High arousal: Good for simple, well-practiced tasks
Moderate arousal: Ideal for complex problem-solving
Low arousal: Beneficial for creative tasks and generating new ideas
Experiment with your environment and mental state to find the optimal conditions for different types of learning tasks.
Directness is the idea of learning being tied closely to the situation or context you want to use it in.
Apply knowledge immediately. To maximize transfer of learning:
Engage in project-based learning
Seek out immersive learning experiences
Use simulations when direct practice isn't possible
The Transfer Problem. Research shows that knowledge often doesn't transfer well from classroom settings to real-world applications. Combat this by:
Identifying how you'll use the skill in real life
Structuring your learning to closely mimic those situations
Regularly practicing in contexts similar to where you'll apply the skill
Drill: Attack Your Weakest Point.
Identify bottlenecks. Analyze your performance to find the specific sub-skills or knowledge areas holding you back. Common methods include:
Time slicing: Break down a skill into smaller time segments
Cognitive components: Isolate specific mental processes
The Copycat: Replicate expert performance in one area while simplifying others
Design targeted exercises. Create drills that focus exclusively on your weak points:
Increase repetitions of difficult elements
Vary the context and difficulty of practice
Use deliberate practice techniques to push beyond your comfort zone
Remember to periodically integrate drilled skills back into full practice to ensure transfer.
Testing isn't simply a way of assessing knowledge but a way of creating it.
Active recall. Instead of passive review, regularly test yourself on the material you're learning:
Use flashcards or spaced repetition systems
Practice free recall by writing down everything you remember about a topic
Solve problems without looking at reference materials
Desirable difficulties. Introducing challenges during retrieval practice can enhance learning:
Delay initial testing to increase difficulty (but not so long that you forget completely)
Use open-ended questions rather than multiple-choice
Practice retrieving information in varied contexts
By making retrieval more effortful, you strengthen the neural pathways associated with the information, leading to better long-term retention.
Feedback is harsh and uncomfortable. Know how to use it without letting your ego get in the way.
Types of feedback:
Outcome feedback: Indicates overall performance
Informational feedback: Highlights specific areas for improvement
Corrective feedback: Provides guidance on how to improve
Strategies for effective feedback:
Seek immediate feedback when possible
Focus on the signal, not the noise (look for consistent patterns)
Create high-intensity, rapid feedback loops
Use metafeedback to evaluate your learning strategy
Remember that feedback can sometimes be demotivating if not processed correctly. Learn to separate ego from performance and use criticism as a tool for growth.
Don't Fill a Leaky Bucket.
Understand forgetting. Three main theories explain why we forget:
Decay: Memories fade over time
Interference: New information overwrites old memories
Forgotten cues: We lose access to retrieval pathways
Retention strategies:
Spacing: Spread out study sessions over time
Proceduralization: Turn declarative knowledge into automatic skills
Overlearning: Practice beyond initial mastery
Mnemonics: Use memory techniques for hard-to-remember information
Implement a combination of these strategies to ensure long-term retention of your newly acquired skills and knowledge.
Do not ask whether a statement is true until you know what it means.
Build mental models. Develop a rich understanding of the subject by:
Creating concrete examples for abstract concepts
Explaining ideas in your own words (the Feynman Technique)
Connecting new information to existing knowledge
Challenge your understanding. Regularly test the depth of your intuition:
Solve novel problems that require applying concepts in new ways
Teach the material to others
Seek out edge cases and exceptions to rules
By developing strong intuition, you'll be better equipped to apply your knowledge flexibly and creatively in real-world situations.
Results? Why, I have gotten lots of results! I know several thousand things that won't work.
Embrace a growth mindset. View your learning abilities as flexible and improvable:
Try different learning methods and resources
Explore various techniques within your chosen field
Push yourself outside your comfort zone
Strategies for experimentation:
Copy, then create: Start by emulating experts, then develop your own style
Compare methods side-by-side: Test different approaches simultaneously
Introduce new constraints: Force yourself to solve problems in novel ways
Find your superpower: Combine unrelated skills for unique advantages
Explore the extremes: Push ideas to their limits to gain new insights
Remember that failure is a natural part of the experimentation process. Each "unsuccessful" attempt provides valuable data for refining your approach.
