composing lyrics

an experience of creating lyrics on set of beautiful chords.....how bad it can be ??
Worst in my case .......Yesterday I had full freedom to choose any word i like to put to create a pattern of lyrics..n what i did......not even able to utter a single line out for any of 2 verses.."A SINGLE LINE"....
Well ok everybody cant do everything...i can create some beats for the song...i hope
