Li Guang is a famous Western Han dynasty, known as the parachutist. The shooting of his stone is seen in the "Historical Records", which is transcribed as follows: "Guang Chu hunts, sees the grass in the grass, thinking that the tiger shot it, and the stone is not stunned. Look at it, the stone also. What s more, I ca nt re-enter Shiyan. Although it s all the effort, the result is very different. The reason is not difficult to understand. Li Guang began to mistake the stone as a tiger. Because it is related to life and death, the potential in the body is all He was excited, so he could shoot the arrow into the stone. After he figured out that it was just a stone, not a tiger, his mentality had changed, so no matter how hard he tried, the arrow that was fired "cannot return to the stone ". What does this tell us? ['Human potential is infinite.', "Li Guang's shot into the stone is a fluke.", "As long as you work hard, nothing can't be done.", 'The exciting potential is conducive to greater success.']
