I love lists of books. Just went through the list of Time Magazines All-time 100 Novels (in English from 1923 to the present). I had read about 50 and plan to put a few on my list.
Another blogger's list has Joyce and Proust at the top, as would mine. If you can't quite get into Ulysses, yet, try Joyce's short stories or A Portrait of the Artist as a Young Man.
You owe it to yourself to read widely, greatly, omnivorously.
Right now I'm reading Eat, Pray, Love, and the Tin Roof Blowdown. Both are very good reads.
What are YOU reading?
