The real key is recognizing when you are wrong and being comfortable admitting it. Because here’s the thing: Being wrong is an opportunity to learn something. Or, to put it another way – you can’t learn without being wrong, because wrong implies you don’t know what you’re doing, which turns out to be the perfect state for learning!
The problem is some people interpret their lack of knowledge as a sign they are dumb, which isn’t the case at all. There’s a difference between not knowing something and being dumb. In fact, I would argue that not being able to admit you are wrong is a better indicator of personal deficiency than a lack of knowledge.
Not knowing is a great place to be – because it means you are primed to learn. It’s how we grow as human beings. So if anyone makes fun of you because you don’t know something, don’t ever be embarrassed, be grateful. They showed you something about their character (insecure because they probably lack some quality they see in you), and they have provided you with an opportunity to learn something you didn’t know.
Take that opportunity and remember not to be an asshole to other people – help them instead. Trust me, life will be a lot more rewarding…
