- [A Local Business Lost $300k SGD to an Email Scam. Here Is How It Happened.](https://kevinchia.sg/blog/business-email-scam-300k-sgd-how-it-happens): A 30-year-old Singapore fashion company lost $300k SGD to a business email compromise scam. The hacker was already inside their system. I break down exactly how it happened, and share a near-miss from my own business that turned out to be completely legit.
- [Ninja Van is Dying. And It Has Nobody to Blame But Itself.](https://kevinchia.sg/blog/ninja-van-is-dying-and-it-has-nobody-to-blame-but-itself): Ninja Van raised over a billion dollars, scaled across six countries, and built real logistics infrastructure. Now it is bleeding volume, cutting headcount, and losing sellers to a competitor it cannot out-price. I was a Ninja Van customer for over a decade. Here is what actually happened.
- [Stop Dreaming About Robots. Automate the Boring Stuff First.](https://kevinchia.sg/blog/stop-dreaming-about-robots-automate-the-boring-stuff-first): Everyone romanticises robotics and big automation. A course I took changed how I think about ROI. Then I built something small in under an hour that actually saved me real time.
- [Everyone's a Guru in a Bull Market](https://kevinchia.sg/blog/everyone-is-a-guru-in-a-bull-market): I've been watching trading gurus, ecommerce experts, and financial educators in Singapore since 2013. Some are fake. Some are real but you are literally funding their next big risk. Here is my personal collection of guru-busting moments from the past 13 years.
- [My Superpower: Dream Specific, Act Early, Get Lucky](https://kevinchia.sg/blog/my-superpower-dream-specific-act-early-get-lucky): I used to call it luck. But looking back at the warehouse, the Bugis shop, Wisma Atria, VivoCity, and our BTO — there is a pattern. Dream specific. Say it out loud. Do the one thing that puts you in position. Then let luck find you.
- [AI for SME Owners: What Actually Happens When You Adapt](https://kevinchia.sg/blog/ai-for-sme-owners-what-happens-when-you-actually-adapt): Everyone says adapt to AI or get left behind. But what does adapting actually look like for a real SME owner? I tried it early, hated it, came back, and ended up building a SaaS product. Here is what I learned and what is actually possible for your business.
- [Vivre Activewear: $10k to $2M, Closed the Stores, Still Very Much Alive](https://kevinchia.sg/blog/vivre-activewear-we-saw-the-end-coming-so-we-left-first): Sylvia started Vivre Activewear with $10,000 and a gap in the market. We scaled it to over $2M in annual revenue, ran stores across Singapore for a decade, and closed every single one on our own terms. Here is how we saw the end before it arrived.
- [The Wheel Strategy: What It Is, What My Real Numbers Look Like, and Why It's Complicated](https://kevinchia.sg/blog/the-wheel-strategy-real-numbers-honest-take): Most people show you the gross premium number and stop there. I'll show you mine, $302k net over 5.5 months, and then explain exactly what that number doesn't include. The full picture is always more complicated.
- [Life Is a Game. So I Built My Site Like One.](https://kevinchia.sg/blog/life-is-a-game-so-i-built-my-site-like-one): I built kevinchia.sg in a day with a full gaming theme. Not because it looked cool. Because life is actually a game and this site is the most honest way I know how to show that.
- [Case Study: "Why do I keep ending up doing everything myself?"](https://kevinchia.sg/blog/case-study-why-do-i-keep-doing-everything-myself): A young entrepreneur kept ending up carrying his business partners. His Bazi chart explained exactly why — and when that will change.
- [You Are Not Broken. You Are in the Wrong Box.](https://kevinchia.sg/blog/you-are-not-broken-you-are-in-the-wrong-box): The script said study hard, get a degree, get a stable job. You followed it. So why does it still feel like something is off? This is not a motivation problem. It is a design problem.
- [Built on a Chart. Corrected by One.](https://kevinchia.sg/blog/built-on-a-chart-corrected-by-one): A single misread chart shaped two decades of decisions. How wrong advice followed since childhood, and how the correction arrived through a zodiac forecast and a gut feeling.
- [How to Use ChatGPT for Human Design (And Why Most People Get Shallow Answers)](https://kevinchia.sg/blog/how-to-use-chatgpt-for-human-design): Using ChatGPT for Human Design but getting generic answers? The chart data going in is the problem. Here is what is actually happening and how to fix it.
- [Human Design Generator: Why You Feel Frustrated (And What To Do About It)](https://kevinchia.sg/blog/human-design-generator-why-you-feel-frustrated): You ticked all the boxes. Good results, stable job, the flat, the car. But every evening you collapse feeling empty. If you are a Human Design Generator, that is not burnout. It is your Sacral center telling you that you are doing the wrong work.
