One small but important habit

Before you send any letter that matters, read it aloud once from start to finish. The phrases that sound wrong in your own voice are exactly the phrases that will sound wrong to your recipient. Reading aloud catches the awkward sentence rhythms that silent proofreading routinely misses, and it forces you to slow down enough to spot the missing word that a fast skim glides over. It takes ninety seconds, and it is the single highest-leverage habit in business writing.
