I'll tell you why that is sad. Because if taken to its logical conclusion your thinking basically equates: everyone is "special" in their own "special" way. They all have their special skills or talents or whatever it may be.
Such thinking completely takes away any incentive for anyone to be a better, more well rounded individual. If I'm already great the way I am, why should I learn more? Why should I try to find out about things that may not have any relevance to what I do? It's hard, and I may not get it at first!
Yes, you can live your whole life not caring about anything other then what you're already familiar with, or even just be happy about the fact that there's a roof over your head and food on your table.
But those of us who are interested in science have one thing in common. We want to know more about the world that we live in, and it's fundamental truths. We seek answers to the most basic questions, such as where we came from, what kind of universe we live in, etc.
I don't think anyone is expecting you to know something obscure like say the albedo of the earth, but I have met plenty of people that don't even know that the sun is a star, or that it's what makes life possible for us.
By thinking about such things we aspire to know more, and not just be content with being just like everyone else.
