The famous American writer Emerson once said: "Confidence is the secret of success"; the great Soviet writer Gorky also once said: "Only those who are confident can be confident everywhere." Immerse yourself in life and realize your own will. "Li Bai, the poet of the Tang Dynasty, "I am born with talent, and I will be useful"; the great leader Mao Zedong's "I will swim three thousand miles into the water"; Shakespeare's "confidence is the first step to success, lack of it." "Confidence is the main reason for failure"; Chaplin's "People must have self-confidence, this is the secret of success". These famous quotes are enough to illustrate: Self-confidence is a huge pillar that can support the vast sky of spirit; The vast sea can lift a giant ship of ten thousand tons to reach the other shore: self-confidence is a ray of warm sunshine that can dispel the shadows in front of us; self-confidence is a ladder that can help us overcome dangers, climb peaks, and have a panoramic view of infinite scenery.
