I'd like to be more articulate...is it possible to learn over 500 new words in a month?

I decided to write down any word i hear that i don't know the meaning of...i get it anywhere off tv, news, friends, and i have over 450 words that ive wrote down and looked up. I just cant remember most of them. Any good strategies in learning and remembering them.. and using them in my day to day conversations?
