The word success is the life goal that people dream of. Discussing the many factors of success, there is no doubt that - as Emerson said: Self-confidence is the first key to success. If you still don't believe it, I can give you an example.
One weekend, both my parents were busy, so naturally the responsibility for the hygiene at home fell on me. First, I have to wipe the room door, bed cabinet, and desk with a rag... After the rag is ready, I officially perform my task. At first I was excited to do it, but it didn’t take long before my mood immediately became irritable. I was just about to give up, but then I suddenly thought of a famous saying I had accumulated, which is what an American writer loves. Merson said, "Confidence is the first key to success." In an instant, I thought confidently that this little chore was nothing. Sure enough, after a while, I finished it quickly.
Confidence is like a kind of magic that will quickly restore you to a good state of mind.
