Nabokov Wrote from 9A.M. to 2 A.M.

I'm proud to say that I had enough discipline to work on Katie for over 10 hours a day during the summer of 2010, which was prompted by examples of amazing feats of discipline that I read about in Creating Minds: An Anatomy of Creativity as Seen Through the Lives of Freud, Einstein, Picasso, Stravinsky, Eliot, Graham, and Gandhi, but I was further amazed when I read the following quote on The Paris Review's website from Vladimir Nabokov:

"For two months in Cambridge I did nothing (from 9A.M. to 2 A.M.) but work on my commentaries to EO [Eugene Onegin]."

That comes to over 17 hours per day! That pales in comparison to my measly 10 hours per day.
