Habits are formed by association, when you repeat something often enough the brain recognizes it as a pattern and that pattern becomes associated with something either pleasurable or negative. As we get older this becomes harder for the brain to accept, so we need to help it along!
Keeping your blog as a positive thing on your task list

Try associating writing your blog with a pleasurable part of your day, maybe you have a cup of your favorite coffee and a couple of biscuits while you write. By a pleasant association you are more likely to enjoy the experience every day. If sitting down and writing becomes connected with a negative experience or feeling you are less likely to want to form that habit. If writing it feels like a chore then you aren’t going to want to sit down and write it!
Build it into your routine. Choose a time of day to write your blog that best suits you and your finest creative brain. Some people work well early in the morning, some in the evening. They don’t take long to update, try allowing yourself some time in your life to write uninterrupted; by allowing yourself some time it does become an integral part of your day. I find the first light of day an inspiration and love listening to the silence of the day before the hustle and bustle starts properly.
Making your environment work for your blogging
It’s also a good idea to make sure working conditions are good for you. Let your friends and family know this is the time that you will be writing your posts and you’d appreciate it if they gave you some peace and quiet for a while. It’s impossible to think when the kids want you to sort out an argument, you’re wanted on the phone or one of the other many reasons our lives are never our own. Shut the door; give yourself some space to think.
Forming the habit of writing it is going to take time, it’s not going to happen overnight, just as a good following won’t. Psychologists recommend doing an activity everyday for 30 days for something to become a habit.
…And that is good advice for a blogger. In order for a blog to work it needs to be updated regularly, every day to start with. Your followers are looking for good and original posts from you regularly. Although you shouldn’t post things just for the sake of a post, that kind of content is less likely to wow than one you actually have something to say in.
Maybe you can’t get to your PC to write sometimes. We all end up with other overriding commitments sometimes. If this happens, try taking a notebook or a voice recorder with you so you can brainstorm at convenient times, when inspiration strikes. Lots of us have this facility on our phones these days – I find both methods useful when I’m out and about, to record ideas that pop into my head.
Keeping the blogging habit alive and well
When it comes to blogging commitments, focus on the positive, not the negative. Rather than dwelling on the posts you forgot to publish, concentrate on tomorrow’s post and make sure that gets done. In order for something to become a habit, you need to think of it in a positive light. If you start concentrating on the negative you will condition your brain to associate blogging with stress, performance anxiety and boredom. Remember we do this for the pleasure, not because it causes us pain!
All habits take a while to form, so give yourself time to get used to your new routine. Keep light-hearted about your blog, and use it as a platform to promote you and your business without feeling overwhelmed by the obligations which regular blogging brings.
