The problem with "they can stink up the joint" is that writing that relies on adverbs and adjectives does stink up the joint. Jazz musicians can break the rules because they both know the rules and understand the rules. Beginners can't break the rules because they don't know when broken rules are ok.

You have to learn how to write without adverbs and adjectives before you can know when to "be judicious in your use of them". Our natural inclination is to use them constantly (see, constantly). Learn how to write without them then the occasional use of them will strengthen and empower your writing.
