I wasn't going to participate in this thread since reading lots of books is no challenge for me. But what is hard, since I have become an ebook hoarder, will be to limit my purchases to a book each week and to buy only books I plan to read immediately. So this is where I'll track those purchases.
Charles Van Doren's Joy of Reading includes a 10-year reading plan. My reading (mostly re-reading) challenge is to complete these books on the Year #1 list:
1. The Iliad by Homer (Fagles translation)
2. The Odyssey by Homer (Mandelbaum translation from Penguin Classics)
3. The Orestia by Aeschylus
4. Oedipus Rex, Oedipus at Colonus, Antigone by Sophocles
5. Hamlet by Shakespeare
6. Long Day's Journey into Night by Eugene O'Neil
7. Waiting for Godot by Samuel Beckett
Beyond those two goals, the plan is to just carry on reading and enjoying books.
