The author spoke about the wait for The Winds of Winterin a recent panel, saying that the popularity of the TV series has caused a few setbacks in the writing process, reported Digital Spy.
"Writer's block isn't to blame here, it's distraction. In recent years, all of the work I've been doing creates problems because it creates distraction. Because the books and the show are so popular, I have interviews to do constantly. I have travel plans, constantly," he said.
Martin went on to say: "I really have to be in my own house undisturbed to write. Through most of my life nobody did bother me, but now everyone bothers me every day.
"I have assistants and minions whose main job is to make sure people don't bother me so I can actually get writing done."
Meanwhile, the author has admitted that he never expected the TV series to catch up so quickly to the books it is based on.
