Aw stuff right. I stuck all my stuff in storage every time I traveled/lived somewhere. Even though I, mercilessly culled stuff I still have mountains. I regret culling my vinyl collection though. I have used commercial freight shipping twice though. Once when I lived in Cyprus and once in Japan.
Fortunately my family didn't leave much to inherit (fortunately? :) ) so there was never really much that was inheritable except worthless nostalgia. Must be hard plowing through stuff and trashing it.
Its incredibly hard, and its ALL worthless nostalgia. The real heartbreak is that my daughter feels no nostalgia for any of it at all. I spent tens of thousand of dollars over the years moving things from house to house, storage units, moving trucks, only to basically sell the units out to flea market dealers for chump change. Watching people drive away with my childhood toys my grandparents gave me, things like that. Just heart breaking. But then I ask myself why? Why does it break my heart, I still have the memories that will die with me, and the stuff was just a big expensive mess id leave behind. But that doesn't make it sting any less.
Photograph the lot and stick it on Hive or Steem. Let the blockchain preserve it forever.
