自信是一种积极的心态，它源自于对自己的能力和价值的认可。拥有自信的人通常能够勇敢地面对挑战和困难，因为他们相信自己具备克服问题的能力。
Self-confidence is the foundation of success. Without it, one cannot achieve goals or overcome challenges. A confident person believes in their own abilities, which drives them to take risks and pursue their ambitions relentlessly. Despite the occasional setbacks, self-belief provides the necessary resilience to keep moving forward. Without confidence, the fear of failure and doubt can paralyze an individual's progress, making success difficult to attain.
