There are many reasons folks don’t write. Lack of talent isn’t one of them.

Deadlines are. Deadlines can make nonwriters, famous writers, and everybody in general, feel all tensed up. A main reason is a deadline makes you promise something you aren’t sure you can deliver. Tense.

Here is a good plan:
1. Calculate the time between now and the deadline.

2. Tell YOU how much time you KNOW it will take you to do this job. EVEN IF you think you don’t know how much time it will take, you DO know. That information is inside you. So, tell yourself “I can come up with something in about 18 hours.”

3. Are there 18 good hours in your life to work on this? If your answer is honestly “no” then you won’t meet this deadline and you have to change it or abandon the effort. It happens to everyone.

4. If you know there are 18 hours, you WILL come up with something. You WILL.

And here is the bonus:
Deadlines do something nothing else can do. They make happen the time when a writer is 100% in one place.
Really, that is all you NEED to do.
Really, it is all that you CAN do.
