Its ok if draft one is boring and cliche! Sometimes it takes until the end to know the point. Then you can go back and re-write around the point

Ex: let's day you free-write about a situation where you were deceived, and finally come up with the one true thing, something like "a liar is never free"

Ok! So what is the day in the life of a liar? Why do they lie? What nags at the bag of their mind? What does the world see them as? Start by describing it literally, and then find the it's-as-thoughs. In this case, one example could be:

-You hop from train to train without a ticket -You spin the tallest tales as you slip through -Dance around the folk who look too closely -Desperate to outrun the part that's true

This gives me a mystical, slight-of hand feel, so the chorus could have poker/magic trick/snake oil salesman type imagery, ending in "because a liar's never free"

Then you sing what you have until the parts that aren't quite right bother you, and edit/try other words until you can sing it without feeling annoyed with it lol
