My frequent offence ... highlighted by the quote from this article below:
Now for a brief list of very, very useless adverbs: the ones often used carelessly as intensifiers. You really should cut these out: “extremely,” “definitely,” “truly,” “very,” and “really.” You can totally use them in dialogue though, especially if your characters are surfers. Otherwise, avoid them mightily.
Now ... to re-write my basic cover letter.
