Writing is difficult. It's one of the most difficult things you can do. Even when you know exactly what you want to say, you're still building an airplane as you try to fly it. So write when you can and even if you don't want to write. Get. One. Word. Down. At. A. Time. Even is you spend 55 min staring at a blank page and 5 min putting down one coherent sentence, you've succeeded.
