If you're talking about adverBs, then you should be carful to use them in the right context, like if somone is feeling sad and does something, then you say that they did it "sadly". Also be careful to use them sparingly. Don't layer up with just adverbs. If you do, the writing becomes a whole lot more dense, and it gets boring to read.
