To be able to write, you need the write tools.
As you appear to be reading this website, I will assume that you already have a computer. If not, then skip the next two items: they are for people with computers. I should say now that computers are not essential for most of the phases of writing, but they sure as hell save a lot of time later on (unless you have a secretary.)
1. Download this program: http://www.spacejock.com/yWriter5.html
yWriter is an incredible (free) tool for creating whole novels out of thin air. You create Chapters and then Scenes in Chapters and then fill them up with words. You can also use all kinds of complicated extra things like Characters, Locations and Items – but I don’t bother. I just focus on the actual writing bit. You can even set a writing targets and the program will chilly-chally you until you’ve finished.
2. Use this website: http://750words.com/
Very very (stupid) simple website that practically forces you to write 750 words a day. You can use this to make sure you write a bit on your novel every day (you get points for hitting 750 words on a day, which then doubles up to make bowling-esque streaks) – or you can just use it like I do for a morning brain dump. Morning brain dumps will make you happier and healthier (apparently), encourage you to get writing and hopefully get all your rubbish words out in one fell swoop, leaving your gold-encrusted mots for the main event.
3. Buy books with blank pages.
This is not a facetious comment. You wouldn’t write in a book that had words in it, so why write in a book that has parallel lines all over the page? How on earth do you hope to write creatively cramped between ruled lines? It just makes no sense to me. Moleskine do nice ones with blank pages. They’re not too big either so will get filled up fast, leaving you with a great sense of achievement. Once you have notebooks, carry them around with you. Note how I use the plural for notebooks. Different notebooks for different occasions. I have little Moleskine ones for portability and big open-up-flat ones for my desk and – important – for my bedside. Always have a notebook by your bed. This is where your best ideas will come. There and on a long walk somewhere. Make sure you have notebooks in these two places.
4. Buy pens.
A lot of pens. Have pens everywhere, in every coat pocket, on your desk, in your hat band – you do have a hat, don’t you? Pens are more important than paper. Paper you can improvise, pens you can’t (without getting blood everywhere.)
So those are your tools. Not too hard, not too expensive. To be honest, the tools aren’t the thing, the thing’s the writing.
