Success is a very lucky thing for everyone, but not everyone can achieve success. Success is not like the pebbles on the riverside that can be picked up everywhere, nor is it like the grass on the roadside that can be found casually. Success cannot be achieved overnight, but there is a long road waiting for us, during which we will encounter many setbacks. As the great French writer Balzac said: "Setbacks are like a stone. For the weak, it is a stumbling block, but for the strong, it is a stepping stone that allows you to stand higher."
