What I mean by that is that your actions can be multiplied a thousandfold, either by broadcasting a podcast or by investing capital or by having people work for you or by writing code. So because of that, the impacts of good decision-making are much higher than they used to be because now you can influence thousands or millions of people through your decisions or your code. So clear mind leads to better (sound) [judgment](Judgement.md) leads to a better outcome. So a happy, calm, peaceful person will make better decisions and have better outcomes.

(similar to Alchemy 煉金術 \& Avocados [^2]) * **The Secretary Problem (The 37 Percent Rule) 撿石子理論** * It implies that the optimal win probability is always at least 1/e (e is Napier’s Constant or Euler’s Number), and that the latter holds even in a much greater generality. * 最佳觀察期為整條路段長度的 1/e ~ 0.36788 (略大於 1/3) * Examples * 擇偶 * 雇員 * 買房 * Note that this theory is not time-based, but [iteration-based](Deliberate%20Practice.md). * [Trust your gut](trust-your-gut.md) --- # [Look for single decision that removes hundreds or thousands of other decisions.](https://tim.blog/2020/01/20/one-decision-that-removes-100-decisions/) > _“Don’t make a hundred decisions when one will do.” — [Jim Collins](https://www.jimcollins.com/index.html)_ * 「哪一種決定是可以把水龍頭🚰關起來的? 」 * [Style is consistent constraint.

Collect constraints you enjoy.](https://stephango.com/style) --- # The 10-10-10 Rule A simple decision-making framework created by author and speaker Suzy Welch. The idea is that you pause and evaluate your decision across three timeframes: * 10 Minutes: _How will you feel about this decision in 10 minutes?_ * 10 Months: _How will you feel about this decision in 10 months?_ * 10 Years: _How will you feel about this decision in 10 years?_ --- # [Two types of decisions](jeff-bezos-letter-to-amazon-shareholders-1997.md) | Type I | Type II | | :-------------: | :----------------------------------------------------------: | | One-directional | Bi-directional | | One-way door | Two-way door | | Irreversible | Reversible | | 三思而後行 | [三行而後思](cultivate-a-strong-bias-towards-action.md) | --- # Two types of decision-makers * **Maximizers:** People who want the “absolute best” option.

They may leave achievement on the table. ## See Also * [Be primarily internally driven](be-primarily-internally-driven-with-intrinsic-motivation.md) --- When faced with any key decision, you effectively choose one of two potential characters: _**Investor**_ or _**Borrower**_. * The Investor is a long-term thinker who makes an investment to [delay gratification](Delayed%20Gratification.md). * Investments compound positively and the future self cashes in on the rewards. * The Borrower is a short-term thinker who takes out a loan to [experience pleasure now](instant-gratification.md). * Loans accrue interest negatively and the future self is stuck with the bill. --- # [The Munger Two Step](https://fs.blog/munger-two-step/) 1. Understand the forces at play. 2. Understand the psychological factors, i.e., how your subconscious might be leading you astray. --- [One filter I use for making decisions: “*How much can I influence the outcome after the initial choice is made?*”](https://jamesclear.com/3-2-1/october-5-2023) * When I can do a lot to influence the outcome, I’m less worried about risk. Even if the choice appears risky on the surface, I can likely create a good outcome with effort. * When I can’t do much to influence the outcome, I’m more risk averse. Even my best effort won’t move the needle. * Your ability to influence the outcome after a decision is made is a crucial thing to consider. --- Razors = heuristics/principles that amplify your decisions = rule of thumbs that simplifies the decision-making process * The Rooms Razor * If you have a choice between entering two rooms, choose the room where you’re more likely to be the dumbest/weakest one in the room. * Once you’re in the room, talk less and listen more. * Bad for your ego—great for your growth. * Related: You don’t have to be the loudest in the room. Just be the one everyone listens to when it goes quiet. * The Arena Razor * When faced with two paths, choose the path that puts you in the arena. * It’s easy to throw rocks from the sidelines. It’s scary and lonely in the arena—but it’s where growth happens. * The Duck Test * If it looks like a duck, swims like a duck, and quacks like a duck, it’s probably a duck. * You can determine a lot about a person by observing their habitual actions and characteristics. * When someone tells you who they are, believe them the first time. * [The Hanlon's Razor](The%20Hanlon's%20Razor.md) * The Hitchens’ Razor \& Newton’s Flaming Laser Sword * Anything asserted without evidence can be dismissed without evidence. * If something cannot be settled by reasonable experiment or observation, it’s not worth debating. * The Bragging Razor * If someone brags about their success or happiness, assume it’s half what they claim. * If a person tells you why their thing (city, relationship, or job) is great, take it with a pinch of salt. * If someone downplays their success or happiness, assume it’s double what they claim. * If a person tells you why their thing (city, relationship, or job) is terrible, take it like a handful of gold. * Beware of Trojan Horses (特洛伊木馬) * The [Luck](luck.md) Razor * When choosing two paths, choose the path that has a larger luck surface area. * Taleb’s Surgeon * If presented with two equal candidates for a role, pick the one that doesn’t “look the part” / with the least amount of charisma. * The uncharismatic one has got there despite their lack of charisma. The charismatic one has got there with the aid of their charisma. --- # [The Cheshire Cat Principle: How to Create Clarity](https://www.sahilbloom.com/newsletter/the-cheshire-cat-principle-how-to-create-clarity) > _If you aren’t clear on where you want to go, any road will take you there._ In Alice’s Adventures in Wonderland, there’s a scene in which Alice reaches a fork in the road and has a simple exchange with the Cheshire Cat: > “Would you tell me, please, which way I ought to go from here?” > > “That depends a good deal on where you want to get to,” said the Cat. > > “I don’t much care where—” said Alice. > > “Then it doesn’t matter which way you go,” said the Cat. --- ## See Also * [Mental Models](mental%20models.md) * [Everything in life has an opportunity cost](Everything%20in%20life%20has%20an%20opportunity%20cost.md) [^1]: _“The mind is difficult to control; swiftly and lightly it moves wherever it pleases.
