Do it. Make the time; make it a priority. Set a goal, literally write it down and put it in your path to remind you. It's like exercising. The more you do it, the easier it gets to go back and work on it everyday. You'll have writer's block and that's okay. That's life. Keep the thought in your mind and ponder on it. Find things that you can draw inspiration from. Learn the creative pattern and process that you have and trust in it.
