I've finally become aware of why I'm so obsessed with the amount of possessions I have. In a book by Peter Walsh (It's All Too Much) he asks one to look at meaning of all the clutter. What I realized is that reducing the amount represents accepting the end of my life. I am acutely aware that when I die all my worldly good will be discarded. Accepting that, I better start accumulating less and discarding these things myself rather than leave it to my heirs to dump.
