A striking proportion of individual investors believe their own stock-picking ability to be above average, a statistical impossibility given that only half of any population can genuinely outperform the rest, yet a pattern that ①persists with remarkable consistency across surveys. This tendency, known as overconfidence bias, leads investors ②to trade more frequently than a more cautious assessment of their own skill would justify. Extensive research comparing the trading records of numerous individual accounts has demonstrated that investors who trade most frequently ③tends to earn substantially lower returns than those who trade rarely, largely because transaction costs accumulate and because frequent trading often reflects overconfident reactions to short-term noise rather than genuine insight. Overconfidence also manifests in the tendency to underestimate the range of possible outcomes, ④causing investors to concentrate their holdings in a small number of assets they feel certain about rather than diversifying across a broader portfolio. Paradoxically, then, the very confidence that motivates investors to act decisively often ⑤undermines the outcomes they are trying to achieve.

When I joined the school broadcasting club two years ago, I only ①wanted to spend time with friends who shared my interests. Gradually, however, the club ②became something much more meaningful. I learned how to write short scripts, operate basic cameras, and ③editing simple video clips for school events. Our club also produced a short documentary about a local market, ④which taught me how much planning goes into even a five-minute video. What began as a casual after-school activity ⑤ended up shaping a clear direction for my future career.

Many large companies now rely on artificial intelligence ① to screen job applications before a human ever sees them. These systems promise efficiency, scanning thousands of resumes in seconds and ranking candidates according to patterns ② drawn from previous hiring decisions. However, this reliance on historical data creates a troubling risk. If a company's past hiring favored a particular group, the algorithm may learn to treat that pattern as a marker of success and quietly reproduce it, even when no one ③ intending discrimination. Unlike a human interviewer, the system offers no explanation for its choices, which makes the bias difficult ④ to detect until an outside audit reveals it. Some researchers argue that fairness cannot be added afterward; it must ⑤ be built into the system's design from the very beginning.

Every morning, our broadcasting club airs a short news program for the entire school. Last Tuesday, I was chosen to read the weather report for the very first time. My hands were ① steady as the red light on the camera turned on. Halfway through my sentence, I suddenly ② forgot the next line completely. For a few seconds, only ③ silence filled the studio, and I could hear my own heartbeat. My partner Minho, who was sitting beside me, quickly slid the script closer to me. I took a deep breath and ④ calmly continued reading from where I had stopped. Somehow, my voice sounded ⑤ steadier than I expected, and I finished the report smoothly. After the broadcast ended, several classmates told me they had not even noticed the pause. That morning taught me that small mistakes rarely matter as much as we fear.

Soyeon joined an online study group chat where dozens of students planned a class project together every evening. When one member suggested skipping a required survey step to save time, several others quickly agreed, and no one raised any objections. Soyeon privately worried that skipping the survey might weaken their project, but seeing everyone else nodding along, she stayed silent rather than risk sounding difficult. The group proceeded confidently, convinced their shortcut was harmless, until their teacher pointed out serious gaps once the project was submitted. Afterward, Soyeon learned about groupthink, a concept introduced by psychologist Irving Janis, describing how tightly connected groups often suppress doubts in order to maintain harmony and reach quick agreement. She realized that ___________.

This kind of outside feedback often reveals strengths you may not notice on your own. Building a career portfolio is a great way to track your growth throughout high school.
