Optimism is one major quality a fisherman must have. A fisherman never knows the kind of fish he would catch, big or small, and he might not even have any catch. But he must maintain a sense of optimism, especially in times of uncertainty, this is the key to his resilience. 

It is also obvious knowledge that fishermen often have an inseparable relationship with water. Without water, there will be no fish, and without fish, there will be no food. It’s a very exclusive connectivity chain.
