the grass is greener on the other side

As I grow older, I am exposed to different concepts and new theories. Which is a good thing, but I find myself questioning every single aspect of my being. I am scrutinizing every single pillar that makes up the foundation of my life - my country's political system, my culture, my people, my religion, humanity. And it makes me want to be younger again, back when all these facts didn't dawn upon me.

Why do we never question? I need to talk to someone smart, major.
