On writting - Arthur Schopenhauer

He who writes carelessly makes first and foremost the confession that he himself does not place any great value on his thoughts. For the enthusiasm which inspires the unflagging endurance necessary for discovering the clearest, most forceful and most attractive form of expressing our thoughts is begotten only by the conviction of their weightiness and truth – just as we employ silver or golden caskets only for sacred things or priceless works of art.
