Let me off you this bit of encouragement: you have already done the hardest thing. The hardest thing that you have done, or will do, for this endeavor is start.
You started! At this point, accept the nerves that will come with this. Accept that the map is not completely laid, the ideas will stutter, and there may even be some days that you think you cannot do this. With you not believing you can’t go on or write another word–when the fear and apprehension try to take hold–do this: breathe.
As hard as it is, I want you to breathe. I want you to remember the thoughts you want to write are yours; the story is yours; the space is yours; you are still in control! Bear in mind the words of James Baldwin: “Not everything that is faced can be changed. But nothing can be changed unless it is faced.”
This is the fear you must face, and face down–this unknown. You must embrace this unsteadiness–it will pass. It will pass as you continue on. You can do it. Keep going.
