"There is no man so blind as one who has made up his mind"

This quote by Brian Herbert is a pointer that our minds can be our own worst opponents. It suggests that when we comprise our minds about something, we become so entrenched in our own beliefs that we end up being blind to any other viewpoint. We end up being so focused on our own perspective that we are unable to see any other possibilities. This quote is a tip to keep an open mind and to be ready to think about other viewpoints. It is likewise a tip to be simple and to recognize that we might not constantly be right. By being open to other points of view, we can acquire a better understanding of the world around us and make more informed decisions.
