Don't feel like writing? Don't. This may seem counterproductive. But, try it. If your brain just does not want to write and you have no inspiration, sometimes you just can't force it to produce quality work. If you have a deadline, try taking a walk and then coming back to it. Otherwise, take the whole day off and just have fin. Don't think about writing. Sometimes your eyes and your brain just need something else to focus on besides words, thoughts, and the computer screen. Whatever you get out and do may actually get your brain working on things to write about.
Take advantage of inspiration. When the inspiration does take over, let it. Just keep writing. Unless you have something important to do, don't let those moments pass you by. As I write this, it's 3 a.m. and my brain is still in inspiration mode. I'm not saying you need to stay up that late if that's not feasible for you. I happen to be wide awake and I do write during the graveyard shift sometimes. So, it's no big deal for me. The point is to take advantage of those moments when your brain and fingers are being extra productive, whenever those moments occur for you.
Schedule writing when you'll actually be free to write. This can be a big issue for many freelance writers. Friends and family often don't think of what we do as a job. They think that because we do this at home, we can drop everything and go wherever they want at any time. If you just cannot get it through to your family and friends not to interrupt you at a certain time, try rescheduling your writing around that. I know that you should not have to accommodate them. But it might make things easier for you. Inspiration flows more easily without interruptions.
Take note of your most productive times of day. Whenever inspiration hits you, write down the time from beginning to end. Do this every time for a month. See if you can find a pattern and switch your writing schedule to write at that time on your work days. Some people write the best in the morning, some in the afternoon. Then others, like me, write the best very late at night on into the morning. Writing at your magical time will help boost your productivity and inspiration levels.
Take time off. I know this from personal experience. The weeks that I take one or more days off to have fun with the kids are more productive than those I take less time off. Why? When your body is tired, it also has an effect on your mood. Most freelance writers will agree that it's much easier to focus when you are in a good mood. For me, outdoor adventures and homeschool field trips with the kids will do the trick. As long as we are doing that every week, it keeps our family happy and it also keeps me ready to write.
