There's something in human nature that finds meaning in turbulence, friction, conflict, movement. A sense of being challenged, pushing past limits, propelling into
excitement and change. When you reach a state where you have all your needs met and don't need to go any further, there still remains a sense that there's more left undone. Comfort can be equated with stagnation. It's a Nietzschean notion. A will-to-danger (not to sound too crazy). There's a sense of being domesticated that adds a subtle discomfort to the comfort.
I've worked blue collar and white collar jobs, and it was the blue collar jobs that made me feel more alive, because I was around dangerous tools, hazards, and actuating my body like it was supposed to be outside exposed to the elements. I went home after and my rest felt deserved and truly regenerative, like my body was drinking it in. The white collar work, though it pays better and offers more comfort and is more cognitively demanding, feels at the same time too breezy, too safe.
It seems like a really stupid argument, that things can be bad because they're too good, affluenza and so on, but there's something to it.
