Trying to get back into the habit of writing daily is a difficult task. Considering all the writing courses that I took in college, you'd figure that writing daily would come easily. When you take even a small break from the task or discipline, it then becomes harder to get back into the habit. Though in college I was taught to write in short snippets, it was that training that helped me start getting my writing back into shape.
So if you're looking for a way to get back to a point of writing daily, then I would encourage you to start with one line, or even a question. When you have a starting point the rest will flow from there. Try reading a few articles and write down a weeks worth to start with, and each day pick up a new line and start writing. It doesn't have to be a long writing session, just 10-15 minutes worth to get the habit back.
