Well, evidently writing is quite easy if you schedule it into your day. I find I get quite a bit of writing done if I start at 11:00 pm and then write to ... well, let’s see, it’s FOUR A.M. NOW.
Some people say you shouldn’t write for a certain length of time, but aim instead at a certain number of words, say 300 (about one page). That’s crazy. I just wrote for five hours and I have three pages.
This is not going to be sustainable, but it is quite exhilarating.
