"There are two insults no human being will endure: that he has no sense of humor, and that he has never known trouble"

This quote by Sinclair Lewis speaks with the importance of humor and understanding of challenge in life. It recommends that a lack of either of these 2 qualities is an insult that no person can endure. Humor is a method of connecting with others and discovering joy in life, while understanding challenge is a way of getting in touch with others and discovering compassion. Without either of these qualities, it is hard to connect to others and to discover meaning in life. This quote suggests that having a sense of humor and having experienced difficulty are vital for a satisfying life. It is an important pointer that we need to make every effort to be understanding and thoughtful towards others, and to find delight in life.
