A writer will never go wrong if he focuses on his own themes, even if he leaves aside many others that could make his work more comprehensive. This comprehensiveness sometimes comes at the price of dispersion. And since the passages in which the writer expresses himself with all the intensity he is capable of are so striking, it is good for him to concentrate on them, to build around them whatever he has to build. Working in this way, even excesses will be diminished by the sincerity that will naturally abound in a work that consciously aimed at the essential.
