We all have opinions. Some more than others. We wouldn't be human without them.
If our opinions are too strong, we don't see clearly. Our opinions are wrapped in emotional bias. They are often formed in part by the influence of other people, the media, schools, churches, personal experiences, and the region we live in. Most times we are unable to see the difference between fact and opinion. Use your opinion as a starting point but don't be attached.
When you see things as they are you don't need an opinion.
"Don't seek the truth, just drop your opinions." Japanese Zen Master
"Only the hand that erases can write the true thing." Meister Eckhart
