If you have a song that has the same progression from the start to the finish.... you can still have well defined verses and choruses.

In the case of a song with the same prog.... you change the melody for the chorus and use notes that are higher in pitch and most listeners will not realize the chord prog is the same.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
