I remember when I was little, I wanted to learn piano, and everyone recommended simple pieces for me to play. They all looked kind of boring, so I printed off the sheet music for Liszt’s Transcendental Etude No. 10 and started practicing.
I can’t say that my skill is anywhere close to that of a concert pianist, but I also can’t say I would have ever stuck with piano if I was forced to practice that other stuff first.
