Peter Gzowski, late lamented Canadian broadcaster and author said, "The art of writing is the art of the application of the seat of the pants to the seat of the chair." J.A. Konrath says, "There is a word for a writer who never gives up....published."
Writing on a laptop that has the ability to connect to the Internet is fiddlin' with the Devil. At the click of a cursor, the author can be doing something far more interesting than describing a character's clothing or a room in a hotel. There are e mails, Facebook updates, Tweets, girls in bikinis, cheap gadgets to buy, auctions to follow, and other author's blogs to read. They are all gifts from the devil.
A resolution to not go anywhere but Microsoft Word for 10 minutes or an hour or two hours, crumbles into dust when the first girl in a bikini walks by or that special camera lens auction is only 10 minutes from ending. No, stronger medicine is called for than mere strength of will.
I have taken to walking to a gazebo 300 feet away in my bare feet across gravel and rough grass, leaving my Rocket Stick Internet connection thingy at home, so I can't get on the 'Net without walking back to get it. That is what works for now. In the winter, I will have to get one of those time locked cigarette packs and put the Rocket Stick in it.
So, how hard is it to write? No hard really, as long as The Devil can be kept at bay somehow.
