Author GRR Martin believes "Game of Thrones", the TV series, "slowed" him down on the path to completing his book series.
The HBO series, based on Martin's series of fantasy novels "A Song of Ice and Fire", aired in 2011 and had its series finale this May.
His fifth and most recent volume of the series, "A Dance with Dragons", was published in 2011 and he is currently writing the sixth novel, "The Winds of Winter".
"I don't think (the TV series) was very good for me. The very thing that should have speeded me up actually slowed me down.
"Every day I sat down to write and even if I had a good day... I'd feel terrible because I'd be thinking: 'My God, I have to finish the book. I've only written four pages when I should have written 40'," Martin told The Observer in an interview
