In response to my post More on the obsession of writing - and personal obsession, Kanani left a comment that is worth quoting from. She wrote:
When I started writing my book, I became obsessed with an area I grew up in but had little real knowledge about. So I became the weird "Delta" lady, reading books about waterways, engineering, marshlands. And later, contacting groups like the wetlands conservancies, and asking them to take me out on boats and such. It was all rather crazy and culminated with me in a truck with a farmer who owned 10,000 acre island farm and told me I was crazy to have ever left.
Isn't that an interesting comment that so well captures the importance of obsession in writing?
