Once you are labeled 'the best' you want to stay up there and you can't do it by loafing around.
I was born left-handed but I was made to use my other hand. When I was writing 'Famished Road ' which was very long I got repetitive stress syndrome. My right wrist collapsed so I started using my left hand. The prose I wrote with my left hand came out denser so later on I had to change it.
