Human Nature: We Are Flawed, But is That Really Bad?

A simple fact: humans are not perfect. We're just not. If we were perfect, there would be no violence. If we were perfect, there would be no disagreements. If we were perfect, we would never make mistakes. Is this the world we live in? No. So are we perfect? Of course not! That's what makes us human: we make mistakes. If everything we did was perfect, then there would be no learning. Wait... does that mean no school? Anyway, if we were perfect, then we would not be fully human. We need to learn to make ourselves better. If we could not get better, everything we do would be so monotonous. That wouldn't be any fun!

My parents preached to me this message a lot. Whenever I made a stupid mistake on a test or something else I was doing, they always told me this to make me feel better. That always worked and still does today. That's how I calm myself down, as well as other people. So yes, we are flawed. But is that really all that bad?
