Curiosity never killed anyone. Maybe mistakes deduced from curiosity led to unfavorable situations, but no one should ever blame curiosity for anything.
In our technological age, we all given access to an innumerable amount of information, given that we have the privilege to access such technology. Even then, libraries are free to the people and offer to us just as good information, if not better, but in a way that is lost to a lot of us. Besides that, the information and knowledge that is so easily accessible to us is overwhelming at times—so much so that I sometimes don't know where to begin. But when you actually think about what we are capable of learning, it seems as though we have the whole world in the palm of our hands.
It is easy to go about our lives in comfort. We know what we need to know, and that is good enough. There is no need to learn another language or string theory or what are the headlines news across the world. Most of us could contently live without ever branching out our knowledge.
To me, learning is exciting. I can admit that I can be a know-it-all, and some of my friends are quick to reassure me of it, but it is mainly because what I do not know frustrates me, even the little things—the things I never needed to know. I often go out of my way to learn about something. As trivial as it may seem, my curiosity often gives me an insatiable hunger for the unknown. And once I know that information, if I find it relevant to whom I am talking or in a certain situation, I am fast to share it.
I am unbelievably pretentious to wish that more people were more curious; that we all shared the same fervor for knowledge—in a curious way, not power hungry—but with the intake of knowledge, comes many great things for us all. Having a better understanding of any such thing broadens our horizons, and I can't help but think that it leads to a sounder foundation for us where we can grow and learn in good, big ways.
My advice would be to start off simple. Expand on what you already know. Master that piano song or read up on that dinosaur that you were once fascinated with as a kid. I think it becomes a snowball effect after that. You'll start getting curious about stuff in which you never showed interest. You'll go back to your Google search history from 2 a.m. and wonder why in the world you wanted to know about peasant life in the Dark Ages.
So stay curious, my friends. Learn all that you can during your time on this mysterious planet; there is a lot out there.
