Do you want to do this thing? Sit down and do it. Are you not writing? Keep sitting there. Does it not feel right? Keep sitting there. Think of yourself as a monk walking the path to enlightenment. Think of yourself as a high school senior wanting to be a neurosurgeon. Is it possible? Yes. Is there some shortcut? Not one I've found. Writing is a miserable, awful business. Stay with it. It is better than anything in the world.
