Graham Greene advised writing 300 words a day. It works out at 2,100 a week, and 109,200 a year. I have a target of 500 words a day. The most I ever wrote in week was 8,000, but my average is about 2,500-3,000. I think long and hard about every word I write..
Sorry for the typos above. I just got an ergonomic keyboard. Takes a bit of getting used to.
I don't set a target. Focusing on a word count is distracting. I aim instead to work of the puzzle of whaterber it is I am trying to write or say.
So I ask myself:
What am I tring to achieve with this piece?
How can I best say it?
What language works best?
Can I play around with things?
The number of words is incidental.
I find aiming for a wordcount (which I used to do when I first started out) left me with too much superfluous text and a load of editing that I found too cumbersome to deal with.
Some days I may only get a paragraph. But if that paragraph tickles my brain and I enjoy reading it, then a paragraph is enough.
I also have days where I write for hours on end and reach 2-3 thousand words. But that is very taxing as I write and edit and purge as I go - exhausting stuff.
I aim for 1000 words a day. It enabled me to finish my children's novel in a month.
