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."

Your boss may think you're not capable. "When I hear employees say they will 'try to meet a deadline,' 'try to close a deal' or 'try to handle a customer issue,' my next question is what do we need to do to ensure their success," says Hoover. "When asked to complete a task that you do not feel is realistic, it's better to suggest a more feasible goal. Managers appreciate problem solvers and employees who come to the table with solutions rather than problems."
