Stay strong. Focus on the ultimate goal.
When a writer first begins to write, he or she feels the samefirst thrill of achievement that the young gambler or oboeplayer feels: winning a little, losing some, the gambler sees theglorious possibilities, exactly as the young oboist feels an indescribablethrill when he gets a few phrases to sound like realmusic, phrases implying an infinite possibility for satisfactionand self-expression. As long as the gambler or oboist is onlyplaying at being a gambler or oboist, everything seems possible.But when the day comes that he sets his mind on becoming a professional, suddenly he realizes how much there is to learn, how little he knows.
Keep your whole being on the thing you are turning into words. The minute you flinch, and take your mind off this thing, and begin to look at the words and worry about them... Then your worry goes into them and they set about killing each other. So you keep going as long as you can, then look back and see what you have written. After a bit of practice and after telling yourself you are going to use any old word that comes into your head so long as it seems right, you will surprise yourself. You will read back through what you have written and you will get a shock. You will have captured a spirit, a creature.
