This sounds really sad. I really hope that you can build memories that are worth spending some time remembering with joy.

> But I find the obsession with nostalgia in our culture to be sad and destructive

My occassional evenings spend looking back through the life that brought me where I am are sad and destructive?

I find them to be very effective tools for reflection.

Re-read what you quoted, please. I did not say "individuals occasionally recollecting their past experiences is destructive." I said the cultural level obsesssion with nostalgia. There's a big difference.

Is there? What do you consider the cultural level obsession then?

You seem to be conflating reminiscence with reflection.

I agree that one is usually concerned with more recent information (hence the effectiveness of the LRU caching heuristic). However, looking back at past endeavours has been a source of new ideas and joy (reminisce achievements) for me. I don't do it frequently though. Maybe once a year or once every two years. Revisiting your past serves as revision as well (you get to see concepts you once used in your work/life).

I wouldn't say nostalgia is sad or destructive, but it is also not for me.

I delete everything when I'm done with it. I backup less than 2 GB of personal data. I have around 100 photos of my entire life, and I'm certain I'll get around to deleting all of them too.

I agree. The past is useful for post-mortem, learning from, but it's too easy to yearn for it in lieu (low agency) of moving forward (high agency).
