I used to save everything I did in the past. Over time, I've found that I almost never needed to access those files and most of that wasn't even useful for the kick of nostalgia. Old games? I already replayed them to exhaustion.

I learned that the nostalgia is not about the files by itself but my life context at that time. I don't miss old code or Old OS's. I miss that sense of wonder when I was less experienced and more naive, and everything was new.
