I fear dying in the middle of a book. It would be so annoying to write 80 000 words and not get to the end. I'm phobic about it. So when I'm writing a book I leave messages all over the house for people to know how the story ends and then someone can finish it for me.
Anything you cannot relinquish when it has outlived its usefulness possesses you and in this materialistic age a great many of us are possessed by our possessions.
