Story:
During the Spring and Autumn period, Confucius often taught his students to learn from Yan Hui, advising them not to pursue wealth and pleasure, but to diligently focus on their studies.
Confucius said that if a person eats their fill all day long with nothing to do, and doesn't apply their mind to thinking about problems, then they will achieve nothing.
Even chess players, though seemingly idle, must use their minds; they are far better than those who eat their fill all day and have nothing to apply their minds to.
