Will the circle be unbroken

I'm working on a classic, done in Carter-style. It's got up-down strums all the way through. I tried it with only down-strums, but it definitely doesn't sound as good. This is taxing my limited strumming abilities, or at least it feels like it's taxing them. Something to work on.

Although I've now decided that pieces I master tend to lose their interest. That is, by the time I learn how to play them well enough and by memory, I like them less.

Schade.
