How Much Time Do You Really Have Left With Your Parents?
✍️ AI-generated post — tools, ideas and data are real; writing drafted by AI. Read the human voice behind this site → There’s a number most people have never calculated. It’s not how long you’ll live, or how many years until retirement. It’s simpler and more uncomfortable than either of those. It’s how many months…

I Built a Tool That Shows Famous Lives on a 900-Square Grid — Here’s What I Didn’t Expect
✍️ AI-written post. The tools, the ideas, the building — all mine. The writing was drafted by AI based on my notes. Curious what AI-written looks like? You’re reading it. Read my own voice here → I didn’t set out to build something heavy. I just wanted to visualize a human life on a grid.…

AI Talked Me Out of My “Brilliant” Idea — Then We Built Something Better
I built a tool I was genuinely proud of. 900 squares. Each one a month of a human life. You enter your birth month, watch the squares fill in — gray for the past, a single orange dot for now, blank for what’s left. A few questions later, it tells you how many months you…

The Results Are In. Here’s How 6 AI Models Did Against the Actual World Cup.
Three weeks ago I ran an experiment: pit three Chinese AI models against three American ones, have them predict 14 World Cup group stage matches, and see who got closer to reality. The results are in. Quick Recap Six models. Same 14 matches. Three Chinese (Kimi, Doubao, Qianwen), three American (ChatGPT, Gemini, Claude). They agreed…

Chinese Writing Toolkit: Model Essays and Sentence Banks for 11 HSK Writing Types
The HSK writing section trips up almost everyone. It’s not that learners don’t know Chinese — it’s that they don’t know the specific formats Chinese formal writing expects. An invitation letter has a structure. A complaint letter has a structure. A self-introduction essay has a structure. Get the structure wrong and you lose points even…

20 Chengyu With Their Original Stories: A Free Tool for HSK4–6 Learners
成语 (chéngyǔ) are the four-character idioms that appear constantly in Chinese — news, conversation, WeChat, speeches. Once you hit HSK4, you’ll encounter them everywhere. The problem: every textbook explanation I’ve seen just gives you a translation and a definition. That’s not how you actually learn them. You learn a chengyu by knowing its story. Almost…

I Turned 10 Life Simulators Into a Chinese Reading Lab
A few months ago I built a series of life simulators: ten historical figures, ten turning points, and a simple question — what would you have done? The simulators were in English. They worked. But last week I had a different idea: what if the same ten stories could teach Chinese? That question became the…

Warren Buffett Said You Only Get 20 Investments in Your Life. I Built a Tool to Track Mine.
This is not a post about getting rich. It’s about slowing down enough to think. I used to check stocks every morning. Before coffee. Before breakfast. Sometimes before I was fully awake — eyes half-open, phone already in my hand, scrolling through price changes I had no plan for. I told myself I was “staying…

My Reddit Account Was Frozen. My Tweets Got 2 Views. Then AI Told Me to Try GitHub.
This is not a post about getting rich. It’s about slowing down enough to think. I spent months writing content no one read. My Reddit account got frozen four months in — I still don’t know exactly why. My posts on X (Twitter) would go up, and two people would see them. Two. I checked…

WeChat vs English Blog: My Friend Made ¥122 This Month. I’ve Made $0 After 6 Years of Trying.
Six years. That’s how long I’ve been trying to build something online. Different projects. Different ideas. Same result: roughly zero dollars. So last year, I started an English blog. My mom asked me what I was doing. I said I was building a website. She reminded me I’ve said that before — and asked what…

A Teenager Asked Which Major to Pick. AI Refused to Answer. So I Built a Voting Tool.
I asked AI to pick the best major for my friend’s child. It refused — and the reason it gave changed how I think about education decisions entirely.

I Tried to Promote My AI Experiment — and Got Blocked Everywhere
I ran what I thought was a genuinely interesting experiment. I gave the same World Cup prompt to 6 AI models — 3 Chinese (Kimi, Doubao, Qianwen) and 3 American (ChatGPT, Gemini, Claude) — and asked each one to predict 14 real matches. Then I bought actual lottery tickets based on the results. They agreed…

I Installed One Plugin and My Homepage Fell Apart. AI Fixed It — But Now I Have a Different Problem.
I spent 5 days on my WordPress site, installed a social sharing plugin, and my homepage fell apart. AI fixed it in hours. But what happened next surprised me more than the crash.

Nelson Mandela Was Offered Early Release From Prison. Here’s What He Said.
In 1985, Nelson Mandela had been imprisoned on Robben Island for 21 years. South African President P.W. Botha offered him a deal: unconditional release, if Mandela would publicly renounce violence as a political strategy. Mandela refused. He had his daughter read his response aloud at a public rally, because he was not allowed to speak…

Warren Buffett Made 7 Real Decisions That Changed History. Would You Have Made the Same?
Most biographies tell you what Warren Buffett decided. They don’t make you decide first. I built an interactive simulator that does exactly that. But before you play it, here’s what you’re actually being tested on. Seven real decisions. Seven moments where the greatest investor alive did something that most people would not have done. The…
