It may take a lot of patience and hard work for you to give one poem a lot of your time, that is if you want to win.

Or on the other hand, you can continue writing as it comes, and who knows, when you least expect it, one of your poems may win a ticket to the front page. Sometimes all it takes is to write, not to win, but for sake of just writing what one feels.

^ Those are my humble of opinions.

An honest write - just keep doing what you're doing. But remember - primarily it's about the poetry, not winning. Write for the joy of it and everything else will follow.
Take care
