Does the subject want to ask "what is the famous saying about contentment?" No chair is comfortable for dissatisfied people.

This sentence was put forward by Franklin, which means that dissatisfied people, even sitting in comfortable chairs, will feel uncomfortable because of their inner dissatisfaction. This sentence is consistent with the view that contentment does not necessarily lead to happiness. That is, people do not pursue too much material wealth or power position, but learn to be satisfied with what they have and enjoy the simple happiness in life.
