To get started efficiently with any business message, writers need a single purpose. The document itself should have only one point, each paragraph that follows should have only one supporting point, and each sentence should have only one focusing point. Easier said than done? No.
One approach to achieving this objective is to heed the advice of "A (Very) Simple Way to Improve Your Writing" by Mark Rennella in the Harvard Business Review. The article, an easy five-minute read, systematically breaks down the writing process for a practical method that successful writers already use, and developing writers should. WORDS ON THE LINE is loaded with nearly 20 years of similar suggestions.
