To hone your writing, hire a translator:
Because professional translators charge around 10 cents per word, translating makes you question the value of every sentence.
This reminds me a talk Jeffrey Zeldman gave in 2006 at An Event Apart. I can’t remember the name of the talk (or find a video), but the gist of it was: labor over your sentences and leave in only the words that bring actual meaning. No filler words allowed. I think about Jeffrey’s talk whenever I write.
