Having a fear of writing is normal.
You might be afraid that you don’t have anything new to say. Remember that every writer brings a unique perspective. Besides, some messages need repeating.
You might believe your work isn’t the best quality. Realize that with enough effort and experience it can be better.
You might doubt that others would be interested in your subject or writing style because they are so unusual. Readers are often attracted to what is different.
Believing in yourself is essential.
