I think that it is being suggested that you use appropriately descriptive words, Posha. When you are writing, avoid vague words (mostly adjectives) like 'good, nice, wonderful, terrible, great, interesting' and other words that carry very little real meaning, and look for words that better describe what you want to say. For instance, instead of 'we had a great trip to the zoo', write 'we had an educational trip to the zoo'.
