Find your best writing time: most writers have a particular time of day when they have an easier time concentrating and getting the job done. Be flexible yet consistent.
Find your best writing place: regularly writing in ‘your spot’ (and using that spot only for writing) puts you in a focused mindset.
Establish a healthy environment: make sure you’re comfortable and your posture isn’t warping your spine, and keep the room well lit and ventilated.
Eliminate distractions: avoiding distraction is a choice you alone can make. Know your weaknesses and actively remove them.
Set achievable goals: motivate yourself to keep going with small objectives you know you can accomplish. These small goals quickly add up to surprising results.
Take frequent breaks: get up, walk around, go outside, grab a drink, talk to people. Keep your mind fresh and your body active to avoid burning out.
Plan ahead: if you know what you’ll be writing before you sit down to do it, you’ll be more productive. Try to have at least a list of scenes for the day, or a basic chapter outline that you can follow.
Find alternate ways to stay productive: sometimes you can’t seem to get the words out at all. Don’t give up and waste your writing hours in self-pity! Find something else to do to advance your project and give you the satisfaction of a productive hour.
Establish accountability methods: if you set hourly/daily/weekly goals for yourself, have a strategy to make sure you meet those objectives (friends, prizes, word-count meters, etc.). Find what works best for you.
Keep your writing tools simple: don’t get distracted by the dozens of apps/programs/toys that do everything for your manuscript except get it written. You can color-code your chapter headings later, friend.
Respect your limits: lastly, don’t be too hard on yourself. Put the whip away. Now and then you just need to take a day off.
