The Mirror World and the Four Domains

R — Original Text (Reading)

Success = skill + luck. For some things, skill accounts for a larger proportion, while for other things, luck accounts for a larger proportion. ... The two symmetrical mirror worlds of "certain/uncertain" and "dark/light" are superimposed on each other, dividing the entire space into four parts. ... The so-called "waiting by a stump for a hare" is actually the process of continuously expanding the "Mastery Domain" and investing in the "Risk Domain." Do your human best: do well the part you can control; leave the rest to fate: invest in uncertainty and look forward to the favor of good luck. ... Victory can be known but cannot be forced! — Chapter 11, "You Worked So Hard, but in the End You Still Lost Everything"

I — Methodological Skeleton (Interpretation)

The world is a mirror structure: the left side (skill-dominated, highly certain) and the right side (luck-dominated, highly uncertain). Most people only have survival experience in the left-side world.
The superposition of two dimensions produces four domains: certain/uncertain x known/unknown = Mastery Domain, Blind Domain, Probability Domain, Risk Domain
Mastery Domain(certain + known): strong causality; the strategy is deliberate practice and improving skills. Such as exams, programming, calligraphy
Blind Domain(certain + unknown): there are patterns but you cannot see them; the strategy is to acknowledge ignorance and actively learn. Such as subject knowledge you do not understand
Probability Domain(uncertain + known): you know the possible outcomes but are not sure which one it will be; the strategy is not to bet on a single instance but on the whole, and to make good use of data in decision-making. Such as investing, marketing conversion
Risk Domain(uncertain + unknown): neither the outcome nor the probability of occurrence is known; the strategy is to avoid entering, increase redundant backups, and make lottery-style small attempts
Unified survival law:waiting by a stump for a hare— guard the "stump" (unchanging laws and certainty) + wait for the "hare" (uncertain opportunities)
Ultimate attitude:Victory can be known but cannot be forced— you can predict the conditions for victory, but you cannot force victory itself

A1 — Application in the Book (Past Application)

Wang Xizhi writing the "Lanting Xu": even in the Mastery Domain (calligraphy skill), there is an element of luck—the peak state of the "Lanting Xu" could not be reproduced even by Wang Xizhi himself. But overall, his strength crushed the competition, and he still became the "Sage of Calligraphy"—the strategy in the Mastery Domain is to rely on skill
The Blind Domain of eloquence: you think "good eloquence" just means being smooth-tongued, but behind it there are a large number of theoretical frameworks you cannot see (logical structure, emotional mobilization, rhythm control)—if you do not acknowledge the Blind Domain, you will stagnate
The "buying lottery tickets" strategy in the Risk Domain: invest a small portion of resources (no more than 20%), cut it small enough and invest in enough places, so that the loss of each part does not hurt, and once one wins, you profit—this is the concrete method of "waiting for the hare"
Small-company entrepreneurship: navigating in the Risk Domain requires redundant backups (multiple business lines) + controlling risk exposure, rather than betting on a single direction

A2 — Trigger Scenarios (Future Trigger)

When to use:

Facing an investment decision, unsure whether to bet on one thing or diversify
Choosing a startup/side business, need to assess the level of uncertainty
Reviewing a failed project: was the strategy wrong, was it just bad luck, or were the laws of the wrong domain applied from the start
When making an annual plan, distinguish which things can rely on effort and which require probabilistic thinking
Feeling "I clearly did everything right but the result was terrible," need to judge whether you used the wrong strategy in the wrong domain

Language signals:

"Why did I work so hard and still fail?"
"Is this thing ultimately about skill or about luck?"
"What can I control, and what can't I control?"
"Should I go all in?"
"How do I deal with uncertainty?"

Distinguish from adjacent skills:

vs. potential-energy: potential energy difference focuses onchoosing which mountain to stand on(spatial position), while the mirror world focuses onwhich type of event you are facing(attribute judgment). First judge the domain of the event, then use potential energy difference to choose your position
vs. dialysis-prism: the dialysis prism applies toclearly defined, decomposable problems(domain of control/domain of blindness), while the mirror world applies tosituations with high uncertainty and uncontrollable outcomes(domain of probability/domain of risk)

E — Executable Steps (Execution)

Step 1: Identify which domain the current event falls into

List the key events/projects you are currently facing
Make two judgments for each event: (1) Is the outcome certain? (certain → left side, uncertain → right side) (2) Do you understand the full picture? (understand → upper half, do not understand → lower half)
Classify into the four domains: certain + understand = domain of control; certain + do not understand = domain of blindness; uncertain + understand = domain of probability; uncertain + do not understand = domain of risk
Completion standard: every key event has a clear domain attribution label, and you can state the reason for the classification

Step 2: Adopt the corresponding strategy for each domain

Events in the domain of control: make a deliberate practice plan, invest your main energy, pursue certain outputs
Events in the domain of blindness: find learning resources (books/courses/mentors), admit "I don't know," systematically fill in the gaps
Events in the domain of probability: collect data, calculate expected value, do not bet on a single outcome, use the law of large numbers to make decisions
Events in the domain of risk: assess whether you can avoid entering; if you cannot avoid it, control the investment to ≤20% of total resources, diversify across multiple small attempts
Completion standard: events in each domain have a corresponding strategy document, including specific next actions

Step 3: Execute the unified law of "waiting by the stump for a rabbit"

List your "stumps" (core skills already mastered, verified patterns, certain assets), and make sure to spend 80% of your time consolidating and expanding them
Design your "rabbit" plan: list the uncertain opportunities you are waiting for, each opportunity's investment cost, potential return, and your capacity to withstand failure
Review regularly: are the stumps increasing? Is the bait cost for the rabbits controllable?
Completion standard: there is a "waiting by the stump for a rabbit checklist" currently being executed, the stump part has specific improvement indicators, and the rabbit part has a clear investment ceiling

B — Boundary (Boundary)

Scenarios not to use:

Pure skill improvement scenarios—no need for probabilistic thinking, just go directly into the domain of control and engage in deliberate practice
Emergency crisis handling—no time for domain analysis, act first and review later
Emotional issues in interpersonal relationships—"treating feelings with probabilistic thinking" is cold-blooded and ineffective

Failure modes:

Using domain-of-control strategies in the probabilistic domain: trying to increase investment returns through "more effort," treating gambling as a skill
Refusing to acknowledge risk in the risk domain: treating completely uncontrollable events with a "I can definitely do it" mindset
Excessive conservatism: putting all resources into the "stump" with no investment at all in "waiting for the rabbit," missing black swan-style opportunities
Misclassification: treating probabilistic-domain events as risk-domain (when you can actually collect data), or treating risk-domain as probabilistic-domain (when you think you know the probabilities but actually don't)

Author's blind spots:

The boundaries of the four domains are often blurry in practice, and many events are cross-domain (a project may simultaneously involve factors from all four domains), lacking guidance on mixed strategies
Although the "guarding the stump waiting for the rabbit" framework is elegant, the criteria for determining the "stump" are not specific enough—what counts as a "known correct pattern"?
There is a lack of practical guidance on "how to collect effective data in the probabilistic domain"; in practice, data acquisition itself may be a blind-domain problem
