Great piece for writers on choosing points of view (do read the comments also).
I believe I was seven years old when I discovered opinion versus fact (points of view, in other words).
I was riding in a truck with my uncle, the radio was on and a familiar song began to play by an artist I hadn’t heard sing that song. I told my uncle, “Joe Cocker’s version is the best.” He said, “That’s your opinion.” I countered that it was the truth.
He explained very clearly and with much humor the difference between an opinion and a fact.
I’ve never confused the two since.
