Graham Norton says his new book was a huge leap out of his comfort zone but well worth the risks.
The king of the British talk show's latest book A Keeper looks at the dark side of human nature, covering topics such as loneliness and death.
Speaking with the Mike Hosking Breakfast, Norton said writing his latest book was far more rewarding than writing his autobiography.
"It is something I didn't know I could do, I wasn't sure if I was going to be able to do but ultimately, it is more rewarding."
"An autobiography is interesting because it's how you're going to tell the story. You think 'oh I've captured that quite well' or 'that's a funny part of that story', But you know all the stories, there are no surprises."
"When you go to fiction, you plan it out as much as you can and you plot it and you do all of that, but there are still days when you're like, 'I can't believe what's going to happen in about two pages' and then you're just typing away furiously to get there."
He said his workflow is a wild scramble of inspiration.
"I really enjoyed the process. I enjoyed it a lot more than I thought I would."
"If I see in my diary I've got a day, I will go, 'that's a book day' and I will block it out for the book."
While writer's block may hinder some, Norton says he doesn't have 'the luxury' of experiencing it.
"What you see in that book is what I wrote because you have just got to seize the time you have."
He said writing the book was extremely nerve-racking but he just thought of the 'worst case scenario'.
"I write a book and the world goes 'oh my god that is terrible, that's the worst book ever written' and I'm embarrassed."
"So it would be humiliating but it wouldn't be career ending. So you think am I willing to take that risk? And I am."
This book was a more 'confident' and 'out there' book for the talk show star, who said it was all about 'taking risks'.
Originally from Ireland, Graham Norton said he likes writing books about rural Ireland because it's the world he grew up in and one he 'knows very well'.
