Go toward the fear.
I say that a lot.
Obviously, you shouldn’t go towards something that you feel a rational, personal-safety fear of. Don’t go over the cliff...but do go toward it, do peek over the precipice. And I'm not so much talking about bodily fear.
The fear I want you to go toward is the kind that prevents you from writing.
For me, as a writer, fear is a powerful compass. If I follow the arrow that points to “this is scary and makes me uncomfortable,” I tend to find lots of creative energy that can be channeled in many directions. And truly, even with my bodily fears, such as my severe thalassophobia (fear of deep water), I can still see where there is so much juice for writing!
