Set up a discipline in which you write regularly. This can take many forms, for different people. I like to use my first energy of the day for creative writing, and then I take care of business matters afterward. I am, however, so goal oriented that if I don’t get my chapter written on a particular day, I often find myself writing late at night. When I’m rolling on the first draft of a book, I like to complete at least one chapter a day. More tips: write what you know about, and over-write, then cut the material back. Don’t say the same thing five different ways in your story. Pick the best way of saying it, and don’t be repetitious. Cut, cut, cut! And obtain feedback if you can, from someone you respect. I spent years in writing groups, in which we read our material to each other and critiqued it. It is difficult to write in a vacuum, without outside input.
