Hey man, let me tell you something.. Most of Liszt's pieces are fairly difficult. If you're not willing to challenge yourself a bit more than you usually do, then I think you should leave Liszt away from your repertoire for a while, before you feel confident enough to jump into one of his great creations. I recommend making Chopin's Etude in C# Minor Op. 10 No. 4 your next goal. If you can conquer that, I think you should be able to learn La Campanella or Hungarian Rhapsody No. 2 right after it -- although, I'm not saying either would be a piece of cake after 10/4, but you should AT LEAST feel more confident.
