I am reading it now as well! I always felt like I wasn't ready, but last week I just decided to go for it. It's been on my list ever since finishing "A Portrait of the Artist as a Young Man". The only other prep I did was reading Hamlet... which so far seems to have not been necessary (but am only up to Lestrygonians).

I actually have to credit Joseph Heller for the nudge to start, I had recently remembered a quote in Catch-22 that stuck with me:

"He knew everything there was to know about literature, except how to enjoy it."
