The answer to those three questions is of course: Yes, yes and yes.
Anyway, in the spirit of something being much more fun when undertaken in good company, I therefore urge you to join me! It's too late to join me on the half marathon, but you could sign up here to National Novel Writing Month. All you have to do is write the 50,000 first draft of a novel between the beginning of November 1st and the end of November 30th. That's about 1,667 words a day.
It's easy (it must be - I've already done it twice).
Go on - you know you want to!
