I think it's important to concentrate on what you do best. I don't feel writers should have to do anything other than this unless they wish to. It is a writer's job to create something. It is the task of others to then market it.

On a rather off-topic note, what kind if word volume to you normally achieve on a day-to-day basis?

I'll be honest and say that I only manage a thousand words but I do write that every day. I think having a routine and a schedule is more important, at least to me. There's no point in writing five thousand words three days running and then doing nothing for five or six days.
