Learning Cheatsheet

I. How to Use This Page

Most readers will want to scan for a technique relevant to their current learning task rather than reading the page linearly. The Quick Reference Index supports this. From there, jump to the relevant section for full details.

The deeper background lives across the other pages in the Discovery section. Discovery Basics covers the underlying neuroscience. Learning How to Learn covers the meta-learning frameworks. Rebranding Learning covers the schooling critique. This page is the practical reference.

III. The Neuroplasticity Super-Protocol

Andrew Huberman’s synthesis of the learning science into a practical protocol.

1. Get Alert

• We must be alert to trigger neuroplasticity (sleep later completes the neuroplasticity and learning process). Getting alert involves many mechanisms, but mainly the release of epinephrine (adrenaline) in the brain and body.
• A straightforward way to become more alert: do 25-30 deep breaths (inhale through the nose, exhale through the mouth). Then exhale your air and hold your breath with your lungs empty for 15-60 seconds. Then inhale once and hold your breath. Do not force the breath-hold; start to breathe normally immediately once you feel the impulse to breathe. Whether you rely on caffeine or not, try this before a learning bout.
• The breathing protocol produces genuine physiological arousal through sympathetic activation. The specific durations are approximate; calibrate to your own response. People with certain cardiovascular or respiratory conditions should approach breath-hold protocols with appropriate caution.

2. Get Focused

• Mental focus follows visual focus. To increase your level of focus on the task you are about to do, stare at a point on a wall, screen, or object for 30-60 seconds before starting (you can blink as needed). You will be surprised how this takes effort; that effort you feel is top-down attentional engagement and reflects the activity of neural circuits involving acetylcholine release and other mechanisms.
• Then move on to the task at hand. Expect your mental focus to flicker on and off, especially at the start of a work or learning bout.
• Having your phone off and out of the room and web browsers closed or limited to essential tabs (or better, the internet turned off) helps.
• The visual focus mechanism is well-grounded. The phone-removal advice is among the more supported interventions for sustained focus; the attention economy work in Sapien Automation explains why.

3. Generate Repetitions

• Perform the maximum number of repetitions you can safely do in a given learning bout. For some types of learning, repetitions will be actual repeats of something, such as learning musical scales. For other types of learning, we progress linearly by repeating the same process, such as reading or doing maths problems.
• Regardless, the same principle holds: work to repeat the process a bit faster than is reflexive for you. This helps keep the mind from drifting off task and naturally keeps you alert.
• Repetition is foundational to skill acquisition. The “slightly faster than reflexive” framing is a useful heuristic for staying engaged; it works better for some learning types (motor skills, recall) than others (conceptual understanding, creative work).

4. Expect and Embrace Errors

• Provided they do not compromise safety, errors during learning are valuable because they increase activation of the neural circuits that increase alertness. When we make errors, it feels stressful, but that stress is just an increase in attention that puts us in a much better place to perform and execute learning-related behaviours on the subsequent trial.
• Computational modelling data suggest that an error rate of approximately 15% may be optimal and help determine how difficult to make a task. Do not worry too much about the specifics. Keep doing repetitions, and when you mess up, capitalise on it by doing another attempt while your forebrain is in that maximally attentive state.
• The 85% success/15% error framing is well-supported (Wilson et al. 2019). The error-as-learning-signal framing is foundational and directly contradicts the schooling treatment of errors as failures. 

5. Insert Micro-Rest Intervals (At Random)

• Human studies have shown that when we are trying to learn something, if we pause every so often for 10 seconds and do nothing during the pause, neurons in the hippocampus and cortex engage the same patterns of neural activity that occurred during the actual activity, but roughly 10 times faster, meaning you get more neural repetitions completed during the pause. These gap effects are similar to what happens in deep sleep.
• Randomly introduce 10-second pauses during learning. A ratio of approximately one pause per every two minutes of learning is reasonable, but distribute them at random rather than every two minutes on the minute.
• The micro-rest finding is based on specific motor-learning studies (Buch et al. and related work). The generalisation to all learning types is less established than the motor-learning evidence. Worth experimenting with; the cost is minimal.

6. Use Random Intermittent Reward

• The neural circuits that control rewards are closely tethered to the circuits that control motivation and the desire to pursue things, including learning. The question of how often to reward yourself or others to keep motivation high has a clear answer: make it random and intermittent. Predictable rewards lose their motivational impact quickly.
• The variable reward schedule is well-grounded (the same mechanism the attention economy exploits, covered in Sapien Automation). Using it deliberately for your own learning is the constructive application of a mechanism that’s usually used against you.

7. Limit Learning Sessions to 90 Minutes

• 90 minutes is approximately the longest period we can expect to maintain intense focus and effort toward learning. Shorter bouts are fine, but after roughly 90 minutes, take a break. Space intense learning bouts 2-3 (or more) hours apart. Most people cannot do more than about 270 minutes of intense learning bouts per day.
• The 90-minute limit reflects the ultradian rhythm covered in the Habit Rabbit Hole. Individual variation is substantial; some people sustain less, few sustain more. The 270-minute daily ceiling is a reasonable approximation for intense focused learning, not a hard limit.

8. After a Learning Bout, Do a NSDR (Non-Sleep Deep Rest) Protocol

• Studies on humans show that shallow naps and NSDR can enhance the rate and depth of learning. Within one hour of completing a learning bout, do a short NSDR protocol. Options include Reveri (a zero-cost, research-tested self-hypnosis app), a brief 20-minute nap, or an NSDR script such as Yoga Nidra.
• The NSDR-after-learning finding is supported by sleep and learning research. The specific tools mentioned are options rather than requirements; the underlying principle (rest after learning supports consolidation) is the point.

9. Get Quality and Sufficiently Long Deep Sleep That Night (And the Next, and the Next)

• The rewiring of neural circuits that underlie learning occurs during sleep and NSDR. Think of the learning bout as the trigger or stimulus for the possibility that we might learn; sleep and NSDR are when the actual learning, the neural circuit rewiring, occurs. The goal should be to get sleep right at least 80% of the time. It takes work to get there, but it is well worth it.
• This is the most supported step. Sleep consolidation of learning is among the most robust findings in learning science. The Sleep & Circadian Rhythm section covers the broader sleep architecture. Trying to learn while chronically sleep-deprived is fighting your own biology.

IV. Phase-Based Scheduling

Matching learning tasks to the phase of the day when your neurochemistry supports them. From the Huberman framework covered in the Habit section.

Schedule difficult learning in Phase 1 when alertness neurochemistry is naturally elevated. Schedule creative and exploratory learning in Phase 2. Protect Phase 3 for recovery. Most people fight their own neurochemistry by scheduling demanding learning at the wrong phase.

V. The 85% Rule

The optimal challenge calibration for sustained learning and development.

• Aim for approximately 85% success and 15% failure during deliberate practice
• Too easy (near 100% success) produces no growth; the system isn’t challenged
• Too hard (well below 85% success) produces no progress and eventual quitting
• When tasks become too easy, increase difficulty until you return to 15% failure
• When tasks become too hard, scale back until 85% success returns
• The 15% failure provides the error-driven neuroplasticity that produces development

This directly contradicts the schooling treatment of errors as failures. Errors at the 15% rate are the entry point for learning, not evidence of inadequacy.

VI. Summarisation Methods

Active engagement with material improves retention over passive consumption.

SQ3R (for reading)

• Survey: Scan the table of contents and chapter summaries for an overview
• Question: Note questions you have before reading deeply
• Read: Read the material in entirety
• Recite: Summarise, take notes, put it in your own words
• Review: Reread your notes, expand them, discuss with others

Progressive Summarisation (for captured material)

• First pass: highlight what resonates
• Second pass: bold the most essential parts of the highlights
• Third pass: italicise the core of the bolded parts
• Final pass: write a brief summary in your own words at the top

The One-Sentence Test

After learning anything, try to summarise it in one sentence in your own words. If you can’t, you haven’t yet understood it well enough. The gap reveals what needs more engagement.

VII. Teaching Methods

Teaching surfaces gaps that passive consumption hides. One of the more reliable learning methods.

The Feynman Technique

• Pick a concept you want to understand
• Explain it as if teaching a beginner
• Identify where the explanation breaks down or gets vague
• Return to the source material to fill the gap, then try again

Implementation Forms

• Teach the material to someone who doesn’t know it
• Write a tutorial as if for a beginner
• Explain the material out loud to yourself
• Record yourself explaining it and listen back
• Tutor others in material you’re learning
• Take turns teaching with a learning partner

The Caveat

Teaching requires having something and somebody to teach. Study first, then teach; the teaching reinforces and tests the study rather than substituting for it.

VIII. Brain 2.0 Integration

• Capture what you learn in a reliable system
• Organise captured material so you can find it
• Connect related ideas to produce emergent insight
• Distill material progressively so the essentials surface
• Express what you’ve learned through writing, teaching, or application

The system compounds across years. Year one feels like work for modest return; year five produces connections and insights that wouldn’t be possible without the accumulated material. This website is an example of this process in action. 

IX. The Daily Learning Pattern

• Morning (Phase 1): One focused learning bout (up to 90 minutes) on the most difficult material, using the full Neuroplasticity Super-Protocol. Get alert, get focused, generate repetitions, embrace errors, insert micro-rests, limit to 90 minutes.
• After the bout: NSDR or brief rest within an hour to support consolidation.
• Midday: Optional second bout if capacity allows, spaced 2-3 hours from the first.
• Afternoon (Phase 2): Creative or exploratory learning, lower intensity, review of morning material.
• Evening (Phase 3): Light review only. Summarisation of the day’s learning. No new intensive learning.
• Night: Quality sleep for consolidation. This is when the actual learning gets wired in.

Most people cannot sustain more than 2-3 intense learning bouts per day. Respect the ceiling rather than grinding past it.

X. The Weekly Learning Pattern

• Most days: The daily pattern, with at least one focused learning bout
• Variation: Vary the material across the week to engage different cognitive resources and prevent staleness
• Review day: One day per week dedicated to reviewing and consolidating rather than acquiring new material
• Rest: At least one lighter day; sustained intense learning without recovery produces diminishing returns
• Community: Regular engagement with a learning community or partner (reading group, study partner, teaching exchange)
• Reflection: Weekly review of what you learned, what worked, and what to adjust

XI. Common Failure Modes

XII. When to Seek Professional Help

Learning difficulties sometimes have underlying causes that self-directed approaches cannot address.

Seek professional assessment if:

• You suspect a specific learning difference (dyslexia, dyscalculia, ADHD) that has never been assessed
• Persistent attention difficulties affect multiple areas of life, not just learning
• Learning consistently triggers severe anxiety or shame beyond ordinary discomfort
• Memory difficulties seem disproportionate or are worsening
• You’re recovering from a brain injury or illness affecting cognition

Appropriate professionals include educational psychologists (learning assessments), clinical psychologists (anxiety, ADHD), and neurologists (memory or cognitive concerns). A specific diagnosis can change the appropriate learning approach; trying harder with the wrong approach produces compounding frustration.

XIII. Apps and Tools

Spaced Repetition

• Anki: Open-source spaced repetition flashcard system. The gold standard for memorisation of discrete facts. Learning curve; payoff for the right use cases.
• RemNote: Notes plus spaced repetition integrated. Useful for learning material where notes and recall combine.

Focus and Sessions

• Forest: Pomodoro-style focus with a tree-planting metaphor.
• Reveri: Self-hypnosis app (research-tested) useful for the NSDR step.
• Brain.fm/Focus@Will: Functional music for focused work.

Knowledge Management (Brain 2.0)

• Obsidian/Roam/Notion: Covered in Brain 2.0.

Learning Platforms

• Specific to your domain: The platform matters less than the practice. The best platform you’ll actually use beats the elaborate one you’ll abandon.

The tools support the practice. The practice is the work. People sometimes spend more time researching learning tools than learning; the tools are not the answer.
