One proverb I would like to introduce is the Korean proverb "세 살 버릇 여든까지 간다." It means that habits formed at a very young age are extremely difficult to change and can last for a lifetime.
There was a time when I had a bad habit of biting my fingernails whenever I felt nervous. I started doing it as a little child, and even as a teenager, I couldn't easily stop. One day, I realized how messy my hands looked and decided to stop making excuses and start taking action. I consciously stopped myself every time I raised my hand to my mouth and tried to break the habit as much as possible.
As time passed, I noticed that my nails were growing back healthier and I was controlling my anxiety better. I felt proud of myself because I was turning my determination into actions. This experience taught me the meaning of the proverb "세 살 버릇 여든까지 간다." I learned that making a habit is easy, but breaking a bad one is what truly requires hard work.
Another expression I would like to introduce is the English idiom "Break a leg." It means that you wish someone good luck, especially before they go on stage to perform.
Last year, I had to give a presentation in front of the whole school, and I was shaking with nervousness backstage. Just before I went up, my friend looked at me, smiled, and said, "Break a leg!" This simple experience helped me understand the meaning of the idiom.
This experience taught me that kindness and support from others can give us great strength. That is why I think the expression "Break a leg" is an important lesson in everyday life.
