"Freedom is cumulative. One choice made with an element of freedom makes even greater freedom possible for the next choice. Each exercise of freedom enlarges the circle of oneself." - Rollo May
I think this applies to what we write as well as to the rest of our lives. When you refuse to self-censor based on what others might think or whether something is more or less likely to sell (do we ever predict that correctly?) you make your circle of freedom smaller.
