Answer:
William needs to find a balance between his professional and personal life.
Explanation:
William is investing a lot in his working life because he believes that this will increase his salary and provide a more comfortable life for his family. However, William's overwork has caused an imbalance in his personal life and has made his family uncomfortable as he has no time for his wife and children.
Even with the salary increase, both William himself and his family will be unhappy because they do not spend a good time together doing some activity that brings them closer. On the contrary, William has been moving his family away more and more.
For this reason, in order to achieve a "right livelihood," William will need to strike a balance between his work life and his personal life. William's salary is important to his family's happiness, but so is his presence.
