time well spent on most of those books

A lot of classics take a lot less time than Lord of the Rings, Harry Potter, or the unfinished Song of Ice and Fire...

... and have a lot more value too... but LOTR is up there.

i thought harry potter, don quixote and crime and punishment were all good investments of my time.  eat, pray, love and the time traveler's wife, however, were life-robbery!

also, it looks like i read at half-speed!

Half speed is good. Means you savor them!
