Choruses? Try not to be too preachy

As I've been seriously engaged in some songwriting for the past few weeks, I'm finding that I have no trouble really writing the lyrics for a verse. Come up with a concept, tell a story, use neat metaphors; that's all easy stuff. The hard part of songs is writing choruses. The problem is, everything that I write comes out like I'm a pretentious, preachy ass, which maybe I am. But that's not what I want to be. And I guess that's not entirely true. I'm ok at writing choruses for songs that are self analytical, or told in the first person, because then the chorus can become a part of the story. The problem occurs when a song tells more than one story. Then the job of the chorus would be to bring together the themes that carry through all of the stories. But it's difficult to do that without being preachy.

Why are people so engaged by a catchy, few word chorus anyway? I guess I can't talk, because I am too. I just can't write them very well. They sound so juvenile. Either my chorus has too many words in it and is therefore difficult to remember, or there aren't enough and I sound two. *sigh* Ah well. Keep plugging away at it, I suppose.

Do you think anyone would like a song about waiting for a plane and observing the people? I don't care; I want to write it. I've even got a chorus in mind for it...
