There should be relentless exposure of and attack upon every evil practice, whether in politics, in business, or in social life. I hail as a benefactor every writer or speaker, every man who, on the platform, or in book, magazine or newspaper, with merciless severity makes such attack, provided always that he in his turn remembers that the attack is of use only if it is absolutely truthful.
I always advise children who ask me for tips on being a writer to read as much as they possibly can. Jane Austen gave a young friend the same advice, so I'm in good company there.
