Hi Stephanie,
It looks like you've already made a start, so you don't need us to start you off!
It's difficult to come up with a boast about you when we don't know anything about you. Obviously we could find a lot of complimentary G-words simply by going through a dictionary, but we don't know which ones would suit you, so it wouldn't be much help. All I can suggest is that you make a list of things that you would boast about, and then look up those words in a thesaurus and try to find synonyms beginning with the right sound.
