Around 2005 I started to fill my amazon wish list with all the books I where liked the idea of having read them. It didn't take very long until I had two dozen or so wish lists (non-fiction subdivided by coarse categories of my interests, fiction subdivided by genres).
Last year I did the math: If I wanted to read them all, assuming I'd read one book per week (a pace that I was able to keep up with when I had no kids), I'd be way beyond retirement age until I could add another book to the list. And given my actual reading pace currently, there was no chance to finish the list in my lifetime. After some soul-searching I discarded all wish lists in an act of liberation from self-inflicted fear of missing out.
