LIVE STREAM: The Simplest Ways to Learn Faster (For Life) + Q&A

Summary

Justin Sung argues that learning faster should be measured by time to the desired outcome, not by how quickly someone covers material. Reading or watching information quickly is only an initial step; the larger time cost often comes afterward, when learners revisit forgotten material, fill gaps, and try to reach deeper understanding. A method that covers material more slowly may still be faster overall if it reduces that later work and leads to stronger mastery.

He illustrates this with a medical student whose new approach initially took longer to get through the material but helped her handle complex cases at a higher level. His point is to judge a learning method by whether it achieves the needed result—not just by its initial pace.

Two Core Methods

1. Increase Prediction Errors

A prediction error occurs when you make a prediction, then discover that it was wrong. Sung describes this as a useful signal for the brain: it highlights where understanding needs to be updated and can strengthen learning.

How to use it:

• Before reading a section or watching a lesson, scan its headings, keywords, or learning objectives.
• Pause and predict what the material will explain—even if you know very little about the topic.
• Make your best reasoned guess, drawing on word meanings and any related knowledge you have.
• Read or watch the material and compare it with your prediction.
• Notice what was incorrect and update your understanding.
• Make another, more informed prediction as you move to the next section.

The goal is to make frequent, thoughtful predictions, not random guesses. Being correct can still be useful because making a prediction engages your thinking, but discovering an error gives you a particularly clear opportunity to revise your understanding.

2. Use Multi-Pass Encoding

Rather than trying to understand every detail on the first attempt, make multiple passes through the material. On each pass, focus on what is understandable and useful at that stage.

How to use it:

• On the first pass, skim and focus on ideas that connect readily to what you already know.
• Don’t get stuck trying to force yourself through every unfamiliar or highly technical detail.
• Let the first pass build a few basic “anchor points” of understanding.
• Return to the material. With those anchors in place, more of the previously difficult content may now make sense.
• Repeat as needed, gradually connecting more of the material.

Sung says prior knowledge strongly affects how easily people can understand new information. He refers to a study involving baseball passages: students who already knew about baseball performed better on the passage than students with stronger reading ability but little baseball knowledge. His broader lesson is that prior knowledge can be built, and that successive passes help expand it.

Other Principles and Advice

• Prepare before consuming a lot of information. Sung says the brain’s working memory is limited, so reading several pages first and planning to make sense of them afterward can leave earlier information difficult to work with. He recommends priming yourself before reading—for example, by previewing material and making predictions.
• Don’t equate writing notes with learning. Writing can be useful, but it does not automatically produce understanding, application, or durable memory. He suggests writing less and being selective about what you record, leaving more time for thinking and processing.
• Start with written material when practicing complex learning skills. Text can be paused and revisited, making it easier to practice comparing and synthesizing ideas. For fast lectures, he suggests judging which points are important, using less important moments to consolidate earlier ideas, and recording only a few keywords.
• Treat a learning system as something to test and revise. A system should work under real conditions, including time pressure and fatigue. If it proves too demanding, identify the point of failure and adjust it rather than abandoning the entire system.
• Aim for effective learning before optimizing for speed or comfort. Learning a skill well may feel difficult at first. Ease and speed often come after repeated practice, not before it.
• Use confusion as a prompt for a question. Sung calls this the “confusion compass”: when you feel confused, ask what specific question, if answered, would reduce the confusion. Answering that question can make the task more manageable and help prevent cognitive overload.
• Make concentration part of the activity. Sung suggests that passive study—such as reading without actively processing—makes it easier for attention to drift. More active tasks, including predicting, making analogies, teaching, retrieval practice, simplifying, mapping, and comparing ideas, can help maintain focus.
• Make reflection actionable through predictions and feedback. Before practicing a skill, predict what action will produce a particular result. Afterward, compare the result with the prediction, identify what may need to change, and test a revised prediction. He also recommends looking for broader patterns that may apply across situations, rather than reflecting only on one specific mistake.
• Apply conceptual understanding to procedural subjects. In subjects such as mathematics and coding, Sung says difficulty often comes from not understanding the concepts behind a procedure, rather than from the steps themselves. He recommends learning the underlying logic and meaning so that learners can recognize when and how to apply procedures. He distinguishes this from truly automatic procedural skill, which may require deliberate practice, including practice under time pressure.
