If you have ever talked to someone who does not have an opinion on anything then you know that it is quite boring.
Such a conversation is quite boring since you have nothing to expound on nor do you learn anything new from the person.
On the other hand when you are engaged in a conversation with a person who has a different opinion from you’re the conversation gets quite stimulating.
A unique outlook is very refreshing to everyone as long as you do not behave like a know-it-all.
