It is said that as an author/writer one must write every day. Well, yes, that is true. It takes self-discipline. How much it takes depends on the person because we’re all different. But if you are one who does not have much self-discipline, it can be learned. You just have to turn it into a habit. How do you do that? By writing every day. I am not going to kid you. Some days it won’t be easy to write because you won’t be in the mood. That’s ok. Do something, anything. Just write. You don’t have to write a lot. Just write. Once writing daily becomes a habit, you will look forward to the task more.
Now comes the question, what if I don’t do any actual writing? What if I am only working in my journal or planning out my story? Yes, those tasks are considered writing. There are times when I am in the middle of writing a scene, and I get stuck. I don’t know how to proceed with the story/scene. So I stop, close out my story, get my shoes on, and go for a walk. On this walk I am thinking about the scene. I let the breeze refresh me and my mind. I allow my characters to ‘walk around’ (so to speak) inside my mind and take a break from the page. When I do this, the answer comes. For you it might not be a walk that you need. It may be something else. My point is that these walks are considered my writing time as well because the story in a way is still being worked on. It also makes the process fun and less tedious.
So, stick with it. Do not give up. Make the process of writing/creating fun. Just stick to it.
