In Dorothea Brande’s classic 1934 guide, Becoming a Writer, she identified four of the key roadblocks afflicting most scriveners. Among the most serious was learning how to get out of your own way:

Sometimes it is self-consciousness that stems the flow. Often it is the result of misapprehensions about writing, or it arises from an embarrassment of scruples; the beginner may be waiting for the divine fire which he has heard to glow unmistakably, and may believe that it can only be lighted by a fortuitous spark from above. The particular point to be noted just here is that this difficulty is anterior to any problems about story structure or plot building, and that unless the writer can be helped past it there is very likely to be no need for technical instruction at all…

You have to keep your audience in mind at all times, of course. But if you don’t listen to your own voice first, there won’t be any audience for you to worry about.
