中国某知识付费平台公布过一组数据：

年收入低于10万人民币的人群，购买课程数量是年收入50万人民币以上人群的3倍；

但课程完课率，前者不足7%，后者高达35%。

穷人不是在买知识，
是在买“我在变好”的幻觉。

背100个Excel公式，比亲手做100张表简单；
收藏100篇写作技巧，比每天写500字容易；
报10门创业课，比摆个煎饼摊轻松多了。

穷人最大的认知陷阱，就是把“输入”当“努力”，把“收藏”当“哈哈拥有”。

真正赚钱的人，都在边流血边总结；
而穷人在等一份“无痛成功说明书”。

iOS 切换商店跳过双重验证

如果你的 iPhone 每次切换 App Store 需要双重验证，或者你想不切换 ID 就能更新不同地区的 App，且不需要密码验证。

可以在设置-邮件-账户，把外区 ID 邮箱添加进去，这样再切换商店就不需要验证了，并且 App 更新也无需再验证密码，直接就能更新，我这么多年都这么操作的，非常方便。

⭐ Happy Chinese New Year!

Following the success of the Chinese startup DeepSeek, many are surprised at how quickly China has caught up with the US in AI. However, China’s progress in algorithmic efficiency hasn't come out of nothing. Chinese students have long outperformed others in math and programming at international olympiads 🏆

When it comes to producing outstanding performers in math and science, China's secondary education system is superior to that of the West. It fosters fierce competition among students, a principle borrowed from the highly efficient Soviet model 🎖

In contrast, most Western schools discourage competition, prohibiting public announcements of students' grades and rankings. The rationale is understandable — to protect students from pressure or ridicule. However, such measures also predictably demotivate the best students. Victory and defeat are two sides of the same coin. Eliminate the losers — and you eliminate the winners ☯️

For many students, motivation to excel in high school comes from treating it as a competitive game, striving to rank first against strong opponents. Removing transparency in student performance can make school feel meaningless for ambitious teenagers. It’s not surprising that many gifted kids now find competitive gaming more exciting than academics — at least in video games, they can see how each player ranks 😵

Telling all students they are champions, regardless of performance, may seem kind — until you consider how quickly reality will shatter this illusion after graduation. Reality, unlike well-meaning school policies, does have public grades and rankings — whether in sports, business, science, or technology. AI benchmarks that demonstrate DeepSeek's superiority are one of such public rankings. And more are coming. Unless the US secondary education system undergoes radical reform, China’s growing dominance in technology seems inevitable 🇨🇳
