Having experience is more important than having an opinion
Everyone has an opinion, opinions are cheap, opinions are biased, opinions are worth shit. Unless the person giving the opinion actually has first-hand, real-life experience.
Yet, we find everyone has an opinion on everything under the sun. Opinions about everything. Things they don’t have a clue about, yet people have an opinion.
Look at me, I know nothing about psychology or why humans do what they do, yet I have an opinion that everyone has opinions.
