The beauty of novel blogging--even if you are the only one who reads it, is that it forces you to think about novel writing. The more regular you are about updating your blog, the more you consider the study of novel-writing, learning to develop your stories to novel length, and actually working on your WIP.
Even if you have only a few minutes a day to devote to your study of novel writing, to actually put words to paper, do it. Make it a part of your daily routine. When it becomes a daily habit, stretch a bit further. Instead of 10 or 15 minutes,write for half an hour.
What I have found is that when I become involved with my writing, I forget everything around me. When I look at the clock, I can scarcely believe how much time has passed.
But too many interruptions and distractions occur that break concentration, even if you have an office in your home. It seems that when you work from home people don't think you're working. And perhaps you begin to think they are right. You feel guilty about taking the time for yourself when someone else needs assistance. Maybe you were raised that thinking of yourself and your needs is selfishness and a cardinal sin.
Set your writing time. Mark it in your day planner in ink--essentially, in stone--and keep that appointment as you would keep an appointment with your doctor, your accountant or any other professional.
If writing at home doesn't work out, go to the local library, a cafe, or even McDonald's,perhaps the park. And don't stop or leave until you have written everything you wanted to get written at this sitting. Make it a habit.
The more you write and meet your goals and make your daily habits, the better you will feel about yourself because your productivity goes up, you hone your writing and editing skills and get closer to the goals.
Let me know how this works for you.
