"人々は自分が物事をできると思い始めると本当に驚くべき存在になります。自分を信じるとき、彼らは成功の最初の秘密を持っています。"

Simplified Meaning:

When people start believing that they can achieve things, they often surprise even themselves with what they can accomplish. Confidence plays a big role in this. For example, think about a student who always thought they were bad at math. One day, a teacher tells them they're smart and capable. Slowly, they start to believe it. They study harder and try more problems, and their grades improve. This change in mindset—thinking they can do better—leads to real success. Believing in yourself is like unlocking a secret door to all your potential. Imagine someone who wants to run a marathon but thinks it's impossible because they've never run long distances before. If they change their thinking and start training bit by bit, that belief encourages them to keep going, and eventually, they complete the marathon. Belief in oneself sparks motivation and drives us to put in effort, leading to success. So essentially, the first step towards any big achievement is having faith in our own abilities.
