"每个人生来都是自信的，但所有东西都会被夺走。"

Simplified Meaning:

When we are born, we naturally believe in ourselves and don't worry about our abilities or value. Babies don’t doubt themselves; they learn to crawl, walk, and talk without thinking they will fail. As we grow up, however, the people around us, such as parents, teachers, and friends, might criticize us or make us feel less capable. This can slowly make us lose our confidence and question our worth. Imagine you scored poorly on a test once and your teacher told you, "You're not good at this subject." This comment can stick with you and make you doubt yourself in future classes, even if you have the ability to improve and do well. Remembering that you were once naturally confident can help you see that you have the power to rebuild your confidence by focusing on your strengths and not letting negative opinions hold you back. You can apply this by taking small steps to challenge yourself and gradually build back your self-belief.
