Just do it. Get it down on the page. Work hard. And then let go. Ask yourself why you want to write. You have to be clear about that.
Yann MartelFor fear, real fear such as shakes you to your foundation, such as you feel when you are brought face to face with your mortal end, nestles in your memory like a gangrene: it seeks to rot everything, even the words with which to speak of it. So you must fight hard to express it. You must fight hard to shine the light of words upon it. Because if you don't, if your fear becomes a wordless darkness that you avoid, perhaps even manage to forget, you open yourself to further attacks of fear because you never truly fought the opponent who defeated you.
