Inside the Workbook
30 days through every section of Brains and How to Get Them
Introduction
Proposes that cognitive capacity is a dynamic, developable equation governed by physical brain cells, mental quality, and active mental force.
Chapter I
Asserts that directed mental energy acts as a physical stimulus that constructs and expands neurological architecture during any cognitive task.
Chapter II
Outlines methods to awaken dormant brain cells, transforming latent neurological capacity into active, functional intelligence.
Chapter III
Explains the fundamental laws of mental cause and effect that transform conscious focus into physical neural growth.
Chapter IV
Provides actionable concentration exercises and somatic drills designed to target and stimulate specific areas of the brain.
Chapter V
Emphasises the physical foundations of mental training: emotional poise, deep breathing, and energy preservation as prerequisites for development.
Chapter VI
Instructs on how to isolate and stimulate targeted brain centres to cultivate specific cognitive talents.
Chapter VII
Explores the connection between conscious intention and subconscious execution in driving physical brain changes.
Chapter VIII
Discusses the subtle mental currents that serve as the primary energetic catalysts for physical cellular growth.
Chapter IX
Teaches how to concentrate deep within the subconscious mind, avoiding the strain and fatigue of effortful conscious mental pressure.
Chapter X
Establishes the governing rules of focused attention and how sustained mental aim accumulates raw neurological power.
Chapter XI
Applies neurological development to commercial success, focusing on building foresight, strategic acumen, and executive function.
Chapter XII
Focuses on storing and multiplying neurological energy to build a highly resilient nervous system capable of sustained high performance.
Chapter XIII-XVII
Outlines how systematic cognitive expansion drives career promotion, and provides specific development protocols for invention, music, art, and literature.
Conclusion
Synthesises the practical system into permanent daily guidelines for maintaining optimal brain health and development across a lifetime.
The Method
Reading the book and doing the work are not the same thing
Most people read Larson's work, agree with it entirely, and then continue doing what they have always done. The gap is not understanding - it is practice. Understanding what the mind needs and consistently doing the work to give it that are two different capacities, and only one of them produces change.
Every exercise in the workbook is built on that distinction. CBT-style thought records identify the specific belief structure underneath a recurring pattern and interrupt it precisely. NLP timeline and future-pacing exercises take a principle from abstract understanding to felt, embodied rehearsal. Somatic check-ins anchor each session in the body rather than the head, because the subconscious communicates through physical sensation, not just through reasoning.
The 30-day structure is deliberate. Habit formation research puts the minimum threshold for a new behaviour to feel natural at 21-66 days, depending on complexity. 30 days sits at the lower end with a full review cycle - enough repetition to shift a default, not so long that momentum collapses before you finish.
How to Use It
Four things that make the difference
- 1
Print it and write by hand
Handwriting activates deeper processing than typing. The motor memory of physically writing a belief, a response, or an intention encodes it differently than keystrokes. Print the workbook and use a pen - it is a functional difference, not a stylistic preference.
- 2
Same time every day
Link the practice to an existing anchor - immediately after your first coffee, or the last thing before sleep. Habit stacking removes the daily decision of whether to do it. The decision is already made.
- 3
Do not skip the body check-in
The somatic prompts at the start of each session are the most skippable-looking part and the most important. What your body is holding at the moment you begin determines how deeply the exercises land. Two minutes of physical grounding before cognitive work changes the quality of everything that follows.
- 4
If you miss a day, continue from where you stopped
Do not restart. Restarting from day one after a miss turns the workbook into a test of willpower rather than a practice tool. The sequence builds on itself - day 15 is more useful after days 1-14, even with gaps.
Worth knowing
This is a practice system, not a reference tool
The workbook takes you through 30 days of structured exercises - it is not designed for quick reference or scanning. If you want the principles in a format you can pin up and return to in 30 seconds, that is what the cheat sheets are for. The cheat sheets are here.
Who This Is For
You'll get the most from this if…
- ✓You believe your intelligence or cognitive capacity is fixed and want a framework for challenging that assumption
- ✓You want to understand the relationship between concentration, attention, and the physical development of mental capability
- ✓You are interested in talent development and want to know what the early self-help movement understood about how expertise is built
- ✓You struggle with mental fatigue, scattered attention, or cognitive burnout and want both a framework and practical recovery tools
- ✓You are a high performer who wants to extend mental longevity and protect cognitive sharpness over decades
- ✓You want the intellectual history behind growth mindset and neuroplasticity - the pre-scientific version that intuited the mechanism before the studies existed

About the Work
Brains and How to Get Them - New Thought, 1866-1954
Larson's guide to developing intelligence, mental acuity, and cognitive capacity - arguing that 'brains' are not fixed at birth but cultivated through specific mental habits.
The Science Behind It
Larson's prolific optimism-based approach is the closest New Thought comes to positive psychology as a formal discipline. His emphasis on the 'promise yourself' principle maps to self-compassion research - treating yourself as you would a good friend is one of the most evidence-backed interventions for sustained positive change. His insistence on consistency over intensity anticipates what we now know about neuroplasticity: small repeated actions create stronger and more durable neural pathways than occasional dramatic ones.
