I find myself using the same adjectives over and over again, despite the thesaurus. I stumbled upon a site (I enjoy stumbling online) while I was doing some research on lists of adjectives. The one I liked best has the adjectives listed and categorized -- I LOVE LISTS.
Momswhothink.com goes beyond just lists of adjectives, there are several types of word lists. Most of my writer friends have been writing a long time. I feel like I'm a rookie among them. I have never been able to memorize things like adverbs, nouns, pronouns, unless I'm doing Mad Libs. This site is great in the simplicity of explanations and how things are organized. Great resource!
