It's no use doubting

It's a Chinese idiom that if you don't have enough confidence in your work, it won't work.

It comes from Sima Qian's biography of Shangjun in historical records of the Han Dynasty: "Kua Yang said:" if you doubt something, you don't know what it is, you can't do it. Moreover, if you have a master, you will see that you are not in the world; if you have a sole concern, you will see that you are in the people. " Many generals said, "good!" Zhang ang drew his sword and struck the ground and said, "today's discussion can't be divided into two parts!" In Sima Guang's Zi Zhi Tong Jian, the first year of the reign of emperor Huaiyang in Song Dynasty, it is used as object and attribute to admonish people
