Of all the priceless objects left behind, this is what we rescue. These artifacts. Memory cues. Useless souvenirs. Nothing you could auction. The scars left from happiness.
Public taste changes and the aesthetic of a culture changes over time, so the idea isn't to appeal to the aesthetic of the moment and what people will like right now; the idea is to somehow keep yourself in the public memory so that as taste evolves it will eventually come to embrace your thing. So, it's about writing to be remembered rather than writing to be liked.
At some point, your memories, your stories, your adventures, will be the only things you'll have left.
