"Never contract friendship with a man that is not better than thyself"

This quote by Confucius is a suggestion to be mindful of the business we keep. It is a warning to not form friendships with individuals who are not much better than ourselves. This might mean that we need to not befriend individuals who are not as intelligent, kind, or effective as we are. It could also imply that we should not associate with individuals who have different worths or beliefs than we do. The underlying message is that we need to aim to surround ourselves with individuals who are much better than us in some method, as this will help us to grow and become better individuals ourselves. By forming relationships with individuals who are more effective, kind, or intelligent than us, we can gain from them and become better versions of ourselves.
