Why do writers, say, give up a job in economics and decide to write poetry? Or, why do they give up a job in a bank and decide to paint, like Krishan Khanna? They want to convey something.

I often feel newspapers are just filling up space. Of course, I also know people who write really long books.

I know from an editor's point of view or a publisher's point of view it's easier to slot me into a particular niche. But I know that I'd be bored unless I wrote a book that in some senses was a challenge.

I tend to follow a scattershot approach to reading a lot of very diverse subjects interest me, and I'm quite happy to read stuff on any of them.
