|There's more than one way to do things|
I've read about 3/4's of the options but other than Harry Potter and War and Peace (of course!), I'll never read any of them again. (though I'll happily watch The Taming of the Shrew)
LOTR - I read as a teenager (who didn't). Thought it very slow and a lot of the descriptive prose truly awful. On given a copy of the book I can make any Tolkien fan squirm with embarrassment within 40 seconds. It is not hard :-)
Foundation - also read when I was a teenager so I guess I was too old to appreciate it.
Steppenwolf - well I guess we all go through that phase.
Gravity's rainbow - was good but not (IMO) worth re-reading.
Where are the Homer, Virgil, Jane Austin, Cervantes and Patrick O'Brian (couldn't resist adding) options?
When the bells justle in the tower
The hollow night amid,
Then on my tongue the taste is sour
Of all I ever did.
