Is expressing opinion essential or not? why?
Expressing opinions helps you build authority and share your perspective with others.
Opinions are important only insofar as they express how we feel so we can tell how other people feel / think / perceive about things.
They help in defining the kind of person you are. Having an opinion shows passion, determination, and knowledge. It shows that you are capable of taking a stand and you are willing to defend something you believe in.
Hope it helps! Pick one sentence ( I would rather pick the first one or second sentence) if the sentence is too long for you to write. Hope you have a good day.
