At some point of the book "On writing" by Stephen King the writer explains the reason.

I quess the question is why.

"Why do I write".

Finished Stephen King's  "On writing " today.

Well it's true that King is not someone who you could call "next in the line up for a nobel prize" .And probably he doesn't want to stand there either after his car accident in 1999 wich he describes on the third section.
