Which are the several most important things in life that cannot wait

Filial piety cannot wait.

People should have filial piety, which has nothing to do with the amount of money or material goods. The most important thing is the bond of family, and the mental satisfaction and joy of elderly parents. Simply put, when your parents get old, offering them a bowl of hot water, taking them for a haircut, or trimming their nails are all acts of filial piety.

Some people don't agree with what I've said. They always think that practicing filial piety requires a material foundation. They believe that since they don't have money right now, they can delay showing filial piety until they become wealthy.

For example, when they were young and studying, they thought it was natural for their parents, who were strong and able to earn money, to support their children's education, and there was no need for children to be filial at that time. After starting work, they thought that as long as their parents were healthy and free from illness, and since they had formed their own families with many responsibilities, they didn't have the means to practice filial piety.
