When I first graduated from college and became a teacher, I believed I was largely responsible for my students’ academic success. I took the job very seriously. I planned every lesson carefully, gave extra homework, monitored their progress, and did everything I could to make sure they studied hard. Whenever a student failed, I thought I knew why. He was lazy. Simple as that. Then something happened again and again. Some of my students came from families I knew well. They were my relatives, my neighbors, or the children of close friends. Their parents cared deeply about education. They supervised homework, limited distractions, and encouraged their children every day. The students themselves weren’t lazy either. They listened carefully. They completed every assignment. They genuinely tried. Yet some of them still couldn’t achieve what I expected. I couldn’t blame the student. I couldn’t blame the family either. I knew I had honestly done everything I could as a teacher. So I was forced to ask a question that had never crossed my mind before: What if academic success depends far less on teachers than teachers like to believe? After digging into decades of educational research, I came to a rather uncomfortable

I’m a big fan of The Art of Thinking Clearly by Rolf Dobelli. But there’s one problem with the book—a good problem to have. It’s packed with so many valuable ideas that it’s impossible to remember them all, even though they’re exactly the kinds of lessons I want to internalize and apply as second nature. After all, that’s the whole point of reading a self-help book. My solution was simple: I compiled one key takeaway from each lesson. Whenever I read through the list, I can quickly refresh my memory and reconnect with the book’s main ideas without rereading the entire book. I’m sharing the list here so I can easily come back to it whenever I need a reminder. If it helps someone else remember these lessons too, even better. Of course, this summary isn’t nearly as entertaining or insightful as reading the book itself, but I hope it serves as a useful companion. Lesson 51 – Hyperbolic Discounting Summary: We prefer small rewards now over larger rewards later. This tendency makes saving, dieting, and long-term planning difficult. Remember: Now beats later. Example: Given the choice between $3,400 today or $3,800 in a month, many people choose the smaller reward immediately.

Lesson 1 – Survivorship Bias Summary: We notice successful people but rarely see the many who failed. This makes success seem more common than it really is. Remember: Look for the invisible failures. Example: Books about successful entrepreneurs ignore the thousands of businesses that failed. 

Nếu con bạn đang ở độ tuổi từ 0 đến 3, hay chính xác hơn là vẫn chưa biết nói tiếng Việt, thì bạn đang có một cơ hội tuyệt vời để nuôi dạy một em bé song ngữ. Bảy năm trước, khi con gái đầu của tôi chào đời, vợ chồng tôi đã đặt ra một mục tiêu: trước khi vào lớp 1, con có thể giao tiếp tốt bằng cả tiếng Anh và tiếng Việt. Tôi đã tham khảo một số tài liệu về việc nuôi dạy trẻ song ngữ. Tuy nhiên, phần lớn những tài liệu đó đều đến từ các gia đình mà bố mẹ có hai ngôn ngữ mẹ đẻ khác nhau. Ví dụ, chồng là người Mỹ, vợ là người Nhật. Trong những trường hợp như vậy, họ thường áp dụng phương pháp One Person, One Language. Nghĩa là mỗi người sẽ nói với con bằng ngôn ngữ mẹ đẻ của mình. Đây rõ ràng là một phương pháp rất hiệu quả. Tuy nhiên, gia đình tôi lại không có hoàn cảnh đó. Tôi có trình độ tiếng Anh khoảng C1, khá mạnh về từ vựng và ngữ pháp nhưng phát âm vẫn còn

A Otters have long, thin bodies and short legs ideal for pushing through dense undergrowth or hunting in tunnels. An adult male may be up to four feet long and weigh around 30 pounds. Females are typically smaller. The Eurasian otter has one of the smallest noses among otter species, with a distinctive shallow ‘W’ shape. The otter’s tail, often referred to as a rudder or stern, is thick at the base and tapers toward the tip, flattening out—this forms part of the propulsion system when swimming quickly underwater. Otter fur consists of two types of hair: stout guard hairs that form a waterproof outer layer and a dense, fine under-fur that functions like thermal underwear. This fur must be kept in good condition through regular grooming. Saltwater reduces the fur’s waterproofing and insulation qualities. That is why freshwater pools are important for coastal otters. After swimming, they wash off the salt in these pools and then rub themselves dry against vegetation. B Scent is important for hunting on land, for communication, and for detecting danger. An otter’s sense of smell is likely similar in sensitivity to that of a dog. Otters have small eyes and are probably short-sighted on
