Greetings, friend. I think I understand what you're talking about. The thing is, we're surrounded by a lot of information. My professor says information is power. I think that with so much information around us, we often tend to choose what best suits our way of thinking. Our mistake is often to assume it's true and not investigate whether it's true.
As you say, sometimes we believe we own the truth because our ego and society have taught us that making mistakes is bad. But I think we also learn from mistakes. Greetings, friend. Have a nice day.
