Analogy and analgous are quite a bit different obviously when it comes down to writing.

Are people essentially good or bad?

'Good' and 'bad' are relative things. And so, are you relating to yourself or some other thing? What thing could you possibly compare/relate with instead of yourself? And good and bad ultimately come down to intelligence although of course not intelligence in the simplistic IQ test way.

The end result is that over and over again, the smarter people are less happy. In part because more and more everyone else appears essentially... not so good. And they can't even say these things and in many cases really honestly even look at them because then they're an elitist for even thinking in terms of their selves as being smarter.

Nostalgia is a longing for return. Most people have nostalgia for their youth. I only have nostalgia for my youth in the sense that it felt as if there was this great hope; of unlimited possibilites. That hope was mostly not real. It is no more or less real than today. Life has slowly taught me how unreal it was.

All of my nostalgia is really just for the return of ignorance. Or at least a bad memory of the reality of the past. This does not mean that it is the same for other people. Other people I suppose had happy carefree childhoods and their nostalgia is legitimate and something entirely different from mine.
