Personally, understanding the "big picture dynamics" of systems is kind of an intellectual porn for me. I loved doing that for as long as I remembered. It always came with the sense of control - understanding the systems means you could tweak it to your liking, if you so desired.
Finally realizing that the system in which we live is basically uncontrollable by an individual within it has blindsided me. So many interesting things happening, so many interesting things that need to be done still, and yet all you and I get to be are observers and consumers of whatever the system happens to spit out.
