The beauty of a piece doesn't depend on its technical difficulty. Back when I used to play classical music more I loved playing a few of Chopin's Nocturnes repeatedly - they were about the right level for me so it was fun, and I could play them pretty well, I think. But I also spent a lot of time learning a few harder pieces (like Fantaisie Impromptu), and I remember getting frustrated that it took me ages to learn them and, although in the end I could play them sortof OKish, my efforts just weren't a patch on what a better pianist could do.
Looking back I can see that I shouldn't have picked such hard pieces until I was really ready for them. It was probably a big part of why I ended up quitting for quite a few years before taking it up again more recently with an entirely different approach.
