So as I was driving to subway to get lunch I started thinking about this. This being what I am about to write of course.
Humans need change. Humans welcome change. Humans bring about change.
Repetition is despised. Repetition causes boredom. Repetition is the absence of change.
If you eat the same food every day for a while, you will eventually get tired of it. If you play the same game every day for a while, you will eventually get tired of it. Anything you do over and over will get old at some point. This can apply to anything, not just activities. Static relationships get boring.
Another interesting fact is that humans hate change at the same time. When things change, most everyone complains. I don't understand this at all. It is in our very nature to get bored from repetition, so we change things, then all we do is talk about how things were better before things changed.
"I remember the good old days when..."
Thinking about the past, reading old things we've written, or watching old home movies gives us that nostalgic feeling. We long for the past, back before things changed.
Alas, why must humans be so paradoxical?
