Remember that by definition, an adjective is a modifier. So any time you want to use one, ask yourself why you need to modify the noun.
If you want to use an adjective, think what its opposite might be. Would you use it then? That can help you decide whether you really need it, or whether that modification can go elsewhere, perhaps where its relevance is clearer.
We’ve often talked about labels; some adjectives act as labels, effectively pointing to the noun as “different.”
