What is the most dangerous word you could ever say at work? It's "try." The word "try" is "short, sweet and fraught with peril," insists Brad Hoover, CEO of Grammarly.com, an automated proofreader and personal grammar coach. Writing in Fortune magazine, Hoover says that using the word "try" -- be it on your resume, in a job interview or to the boss's face -- shows you lack belief, passion, commitment and confidence. He notes there are 66 different synonyms for "try," but "none of them are as convincing as words like do, believe, act, tackle, accomplish or succeed."
