As to the ten books that have made my life worse, I've backed off from compiling that list.
The fault was not in the books.
There are books that have mattered to me unduly because I was in need of such.
Books that have misled me because I needed to be led.
Books that have intoxicated me. Should books be controlled substances? Should you need a script?
Books that are pure shit. When I think of scraping them off I conclude that, too, would be a mistake, since how else would I know where and by whom these stinkers are likely to be deposited?
And then there is aging: I remember Vladmir Nabokov commenting that revolutions should be made only by the old, that only the aged were entitled. I raged against Nabokov for that. But I was so young.
