Many times writing is not thinking at all, many listicles in the web are just stupid thoughts for example, a way to increase the audience. A good writing is when you love the subject you are writing about, which obviously entails that you already master the subject and thus you can make a contribution, it is when the writing comes from your heart that it have the great impact, when your mind is free and your fingers are out of your control (using either pencil or keyboard).
