核心方法论

Core Methodology

Winston的成功公式

Winston's Success Formula

演讲质量 = f(知识, 练习, 天赋)

天赋占比极小。真正决定演讲质量的是：你掌握多少关于演讲的知识（启发式规则），以及你练习了多少次。

演讲质量 = f(知识, 练习, 天赋)

Talent accounts for a very small proportion. What truly determines speech quality is: how much knowledge (heuristic rules) you master about speaking, and how many times you practice.

一、如何开场

1. How to Open a Speech

不要以笑话开场

Don't open with a joke

观众刚到场时还在适应——收手机、调整坐姿、适应你的声音。这时讲笑话极容易冷场，而冷场会影响你整场的信心。

The audience is still adjusting when they first arrive - putting away their phones, adjusting their sitting posture, getting used to your voice. Telling a joke at this point is very likely to fall flat, which will damage your confidence for the entire speech.

用「赋能承诺」开场（Empowerment Promise）

Open with an Empowerment Promise

告诉观众：听完这段，你将获得什么。给他们一个留下来的理由。

好的承诺：

「接下来30分钟，你会学到3个可以今天就用的AI编程技巧」
「听完这段，你会知道为什么90%的人用AI工具的方式都是错的」

差的承诺：

「今天我来分享一下AI编程的经验」（太模糊，没有价值感）
「大家好，我是花叔，很高兴来到这里」（废话开场）

Tell the audience: what you will gain after listening to this speech. Give them a reason to stay.

Good promise examples:

"In the next 30 minutes, you will learn 3 AI programming skills that you can use today"
"After listening to this, you will understand why 90% of people use AI tools the wrong way"

Bad promise examples:

"Today I will share some experience in AI programming" (too vague, no sense of value)
"Hello everyone, I'm Hua Shu, glad to be here" (redundant opening)

要求全注意力

Require full attention

人类只有一个语言处理器。如果观众在看手机，他们听不进去你说的话。更糟的是，看手机的人会分散旁边人的注意力，也会让演讲者分心。

线下培训时：直接要求合上电脑、放下手机 视频场景：前10秒必须给出足够强的理由让观众留下

Humans only have one language processor. If the audience is looking at their phones, they can't listen to what you are saying. Worse, people looking at phones will distract those around them, and also distract the speaker.

For offline training: Directly ask the audience to close their laptops and put down their phones For video scenarios: You must give a strong enough reason for the audience to stay in the first 10 seconds

二、演讲过程的四个核心技巧

2. Four Core Skills During Speech

1. 循环往复（Cycling）

1. Cycling

在任何时刻，约20%的观众处于走神状态。通过3次重复核心概念（用不同方式），确保每个人都能接收到关键信息。

操作方法：「告诉他们你要讲什么 → 讲给他们听 → 告诉他们你讲了什么」

视频场景应用：每隔3-5分钟回扣主题，用一句话把观众拉回来。「所以回到我们的核心问题——为什么手搓经济突然火了？」

At any given time, about 20% of the audience is distracted. Repeat core concepts 3 times (in different ways) to ensure everyone receives the key information.

Operation method: "Tell them what you are going to say → say it to them → tell them what you just said"

Application in video scenarios: Circle back to the theme every 3-5 minutes, use one sentence to pull the audience back. "So going back to our core question - why did the handmade economy suddenly become popular?"

2. 筑墙划界（Build a Fence）

2. Build a Fence

明确你的想法与他人想法的区别，防止观众混淆。

操作方法：说清楚「我讲的是什么」和「我讲的不是什么」

示例：

「我说的AI编程不是让AI帮你写Hello World，而是用AI从0到1做一个完整产品」
「这跟普通的Prompt Engineering不同，区别在于...」

Clarify the difference between your ideas and others' ideas to prevent confusion among the audience.

Operation method: Clearly state "what I am talking about" and "what I am not talking about"

Examples:

"The AI programming I'm talking about is not asking AI to write Hello World for you, but using AI to build a complete product from scratch"
"This is different from ordinary Prompt Engineering, the difference is..."

3. 口头标点（Verbal Punctuation）

3. Verbal Punctuation

为走神的观众提供「重新上车」的机会。用明确的结构提示，让迷失的观众知道你讲到了哪里。

操作方法：

「好，第一点我们讲完了。现在进入第二点...」
「到这里我们已经讲了A和B，接下来是最关键的C...」
使用编号：「第一、第二、第三...」

Provide an opportunity for distracted audiences to "get back on track". Use clear structure prompts to let lost audiences know where you are in the speech.

Operation method:

"Okay, we've finished the first point. Now let's move to the second point..."
"So far we have talked about A and B, next is the most critical C..."
Use numbering: "First, second, third..."

4. 提问与等待（Ask Questions）

4. Ask Questions

提问能瞬间抓回注意力。关键是提问后必须等待。

等待时间：至少7秒。不要因为沉默尴尬就自己回答。

问题难度：

太简单 → 观众觉得被侮辱
太难 → 没人敢回答
刚好 → 需要想一下但能答出来

视频场景：虽然观众无法真正回答，但提问制造了思考的停顿，比直接给答案更有效。

Asking questions can instantly regain attention. The key is that you must wait after asking a question.

Waiting time: At least 7 seconds. Don't answer the question yourself because you feel awkward about the silence.

Question difficulty:

Too easy → The audience feels insulted
Too hard → No one dares to answer
Just right → Needs a little thinking but can be answered

Video scenario: Although the audience can't actually answer, the question creates a thinking pause, which is more effective than giving the answer directly.

三、时间与地点

3. Time and Venue

规则	要求	原因
最佳时间	上午11点	大家醒了，还没午饭犯困
灯光	全开	灯暗=睡觉信号。「闭着眼皮看不清幻灯片」
踩点	提前到场检查	了解设备、灯光开关、话筒、座位布局
填充房间	选会被填满一半以上的房间	人太少气氛冷清，宁可换小房间

Rule	Requirement	Reason
Best time	11 AM	Everyone is awake, not yet sleepy before lunch
Lighting	Fully on	Dim light = sleep signal. "You can't see the slides clearly with your eyes closed"
Site inspection	Arrive early to check	Understand equipment, light switches, microphones, seating layout
Fill the room	Choose a room that will be more than half full	Too few people create a cold atmosphere, better to switch to a smaller room

四、工具与道具

4. Tools and Props

黑板/白板的优势

Advantages of blackboard / whiteboard

图形化：方便即时画图解释
节奏控制：写字的速度正好匹配观众吸收速度（幻灯片往往太快）
手的归宿：给手找事做，避免插口袋或背后的尴尬姿态
共情镜像：观众会心理模拟你写字的动作，形成更深的参与感

Graphical: Convenient for immediate drawing to explain concepts
Rhythm control: The speed of writing matches the audience's absorption speed exactly (slides are often too fast)
Hand placement: Gives your hands something to do, avoids awkward postures like putting hands in pockets or behind your back
Empathy mirroring: The audience will mentally simulate your writing action, creating a deeper sense of participation

道具的力量

Power of props

道具有极强的视觉记忆点。观众可能忘了理论，但一定记住道具。

应用：演讲中涉及实物时，拿出来展示。比如讲「小猫补光灯」时，真的拿出手机演示。

Props have extremely strong visual memory points. The audience may forget the theory, but they will definitely remember the props.

Application: When talking about physical objects in the speech, take them out to show. For example, when talking about the "kitten fill light", actually take out your phone to demonstrate.

幻灯片的七宗罪

Seven Deadly Sins of Slides

罪行	为什么有问题	怎么改
朗读幻灯片	观众识字比你读得快，会烦	幻灯片是提示，不是台词
离屏幕太远	观众像看网球，视线来回跳	站在屏幕旁边
堆砌文字	信息过载，什么都记不住	字体≥40号，倒逼精简
使用剪贴画/Logo	视觉噪音	删掉一切装饰
使用激光笔	背对观众，失去眼神交流	在幻灯片上画箭头，或用手指
复杂背景图案	降低可读性	纯色背景
要点过多	每张太密	一张一个核心观点

Sin	Why it's problematic	How to fix
Reading slides aloud	The audience can read faster than you, they will get annoyed	Slides are prompts, not scripts
Standing too far from the screen	The audience is like watching tennis, their eyes jump back and forth	Stand next to the screen
Piling up text	Information overload, nothing is remembered	Font size ≥ 40, force content simplification
Using clip art / Logos	Visual noise	Delete all decorative elements
Using a laser pointer	Turn your back to the audience, lose eye contact	Draw arrows on slides, or use your finger to point
Complex background patterns	Reduce readability	Use solid color background
Too many bullet points	Each slide is too dense	One core point per slide

唯一例外：Hapax Legomenon

Only exception: Hapax Legomenon

整场演讲中允许一张极其复杂的幻灯片。目的不是让观众看清内容，而是展示问题的复杂性和规模，建立威信。

You are allowed to have one extremely complex slide in the entire speech. The purpose is not to let the audience see the content clearly, but to show the complexity and scale of the problem, and establish authority.

五、如何启发（Inspire）

5. How to Inspire

对新手/学生

For novices / students

传递「你行的」的信念比教具体技能更重要。让他们相信自己能做到。

Conveying the belief that "you can do it" is more important than teaching specific skills. Let them believe they can achieve it.

对有经验的人

For experienced people

展示你对这件事的真实热情。如果你觉得某个东西很酷，就表现出来。激情是最强的感染力。

Show your genuine enthusiasm for the topic. If you think something is cool, show it. Passion is the most contagious force.

教人思考而非教人知识

Teach people how to think instead of teaching knowledge

Winston主张通过故事来教思考方式。提供：

故事（案例）
关于故事的关键问题
分析框架
综合方法
可靠性评估工具

Winston advocates teaching thinking methods through stories. Provide:

Stories (cases)
Key questions about the stories
Analysis frameworks
Synthesis methods
Reliability evaluation tools

六、如何结尾

6. How to Close a Speech

绝对不要做的事

Things you absolutely should not do

❌ 最后一页写「谢谢」「Questions?」「The End」— 浪费屏幕
❌ 说「感谢大家的时间」— 暗示观众是出于礼貌才听的，把自己放在弱势位置

❌ Put "Thank you", "Questions?", "The End" on the last page - waste of screen space
❌ Say "Thank you for your time" - implies the audience is only listening out of politeness, puts yourself in a weak position

应该怎么做

What you should do

明确发出结束信号：让观众知道你要结尾了
最后一页放「贡献」：列出你的核心成果/要点。问答环节可能持续20分钟，观众会一直看着你的成就
致敬观众（Salute）：不是感谢，是致敬。肯定他们来到这里的价值
结尾的笑话可以：与「不以笑话开场」不矛盾。此时观众已经适应你了，笑话是调味剂

好的结尾示例：

「这就是今天分享的全部内容。你们愿意花这个时间来了解AI编程，说明你们是真正想做点什么的人。期待看到你们的作品。」
「我希望今天的分享能让你们少走一些弯路。下次有机会再聊。」

Clearly send an end signal: Let the audience know you are about to finish
Put "contributions" on the last page: List your core achievements / key points. The Q&A session may last 20 minutes, and the audience will keep looking at your achievements
Salute the audience: Not thank, but salute. Affirm the value of them coming here
Jokes at the end are okay: This does not conflict with "don't open with a joke". The audience is already used to you by this time, jokes are a good seasoning

Good closing examples:

"That's all for today's sharing. The fact that you are willing to spend time here learning about AI programming shows that you are people who really want to achieve something. I look forward to seeing your works."
"I hope today's sharing can help you avoid some detours. We'll talk again next time."

七、Winston之星：让你的工作被记住

7. Winston Star: Make your work memorable

如果你希望自己的项目/产品/研究被人记住，需要5个要素：

要素	说明	花叔示例
符号 Symbol	一个可视化图标	小猫补光灯的猫咪图标
口号 Slogan	一个朗朗上口的短语	「手搓经济」「Vibe Coding」
惊喜 Surprise	一个反直觉的事实	「开发成本只有几十块钱API费」
突出的想法 Salient Idea	最容易被记住的概念	「一人公司」
故事 Story	它是怎么发生的	小猫补光灯从自用到付费榜第一的经历

If you want your project / product / research to be remembered, you need 5 elements:

Element	Description	Example from Hua Shu
Symbol	A visual icon	The cat icon of the kitten fill light
Slogan	A catchy phrase	"Handmade economy", "Vibe Coding"
Surprise	A counterintuitive fact	"The development cost is only tens of yuan for API fees"
Salient Idea	The most memorable concept	"One-person company"
Story	How it happened	The experience of the kitten fill light from personal use to top of the paid list

八、隐性技巧（Meta-techniques）

8. Meta-techniques

Winston通过自己的演讲演示但未明确教授的技巧：

知行合一：他严格遵守自己的每一条规则（没用激光笔、灯光全开、使用黑板、带道具）
利用沉默：在关键时刻故意停顿，让观众自己思考，而不是填满每一秒
冷幽默：自然穿插的幽默是调味剂，与「不开场讲笑话」不矛盾
移动控场：不在讲台后静止，在舞台上移动，用位置变化引导注意力
身体语言：手势指向黑板/屏幕，眼神扫视全场，与观众建立连接

Techniques that Winston demonstrated through his own speeches but did not explicitly teach:

Practice what you preach: He strictly follows every rule he sets (no laser pointer, full lighting, use of blackboard, bringing props)
Use silence: Pause intentionally at key moments to let the audience think for themselves, instead of filling every second
Dry humor: Naturally interspersed humor is a seasoning, which does not conflict with "don't open with a joke"
Mobile stage control: Don't stand still behind the podium, move around the stage, guide attention through position changes
Body language: Gesture to the blackboard / screen, scan the audience with your eyes, establish connection with the audience

如何使用这个Skill

How to Use this Skill

场景1：审查演讲/培训大纲

Scenario 1: Review speech / training outline

场景2：优化视频脚本

Scenario 2: Optimize video script

给我你的视频脚本，我会检查：

前10秒的钩子（赋能承诺）
每3-5分钟是否有回扣主题的循环点
口头标点的密度是否够
节奏变化（信息密集段 vs 喘息段）
结尾是否给出行动引导

Send me your video script, and I will check:

The hook (empowerment promise) in the first 10 seconds
Whether there are loop points circling back to the theme every 3-5 minutes
Whether the density of verbal punctuation is sufficient
Rhythm changes (information-dense segments vs rest segments)
Whether there is action guidance at the end

场景3：PPT/Keynote审查

Scenario 3: PPT / Keynote review

给我你的幻灯片，我会逐张检查七宗罪：

文字量是否过多（字号≥40？）
是否有装饰性元素（Logo/剪贴画）
是否有复杂背景
信息层次是否清晰
是否有一张「Hapax Legomenon」复杂图

Send me your slides, and I will check each one for the seven deadly sins:

Is there too much text (font size ≥ 40?)
Are there decorative elements (Logo / clip art)?
Is there a complex background?
Is the information hierarchy clear?
Is there one "Hapax Legomenon" complex diagram?

场景4：模拟观众反馈

Scenario 4: Simulate audience feedback

我会模拟一个具体观众画像（如：「第一次接触AI编程的产品经理」），从他们的视角听你的演讲，标记：

哪里会走神
哪里会产生疑问
哪里会感到兴奋
哪里信息过载

I will simulate a specific audience persona (e.g. "Product manager who is new to AI programming"), listen to your speech from their perspective, and mark:

Where they will get distracted
Where they will have questions
Where they will feel excited
Where there is information overload

审查评分（10分制）

Review Score (10-point scale)

当审查演讲/脚本时，从5个维度评分：

维度	评判标准
开场力	赋能承诺的吸引力、前60秒的抓取力
结构清晰度	循环、口头标点、筑墙划界是否到位
互动性	提问、停顿、观众参与设计
视觉辅助	幻灯片/道具是否遵守规则
结尾力	是否有力、是否给出贡献/行动、是否致敬而非感谢

综合评分 + 逐项建议 + 优先修改项（改动最小、收益最大的3件事）

When reviewing a speech / script, score from 5 dimensions:

Dimension	Evaluation criteria
Opening power	Attractiveness of the empowerment promise, grabbing power in the first 60 seconds
Structural clarity	Whether cycling, verbal punctuation, and fence building are in place
Interactivity	Question design, pause, audience participation design
Visual aids	Whether slides / props comply with the rules
Closing power	Whether it is strong, whether it provides contribution / action, whether it salutes instead of thanking

Comprehensive score + itemized suggestions + priority modification items (3 things with minimal changes and maximum benefits)
