Chopin's 2nd nocturne.
That's the first piano piece I've ever taught myself; it took me around 4 months to learn it, it was quite complicated for two reasons:
1) This is an advanced piece that requires at least 5 years of playing piano, and I had just barely started piano
2) I procrastinate a lot

Chopin - Nocturne Opus 9 N° 2

Chopin's 19th waltz, posthumously published.
That's the second piano piece I've ever fully learned in my now almost one year of learning piano; this is my personal interpretation after 2 weeks of playing it.
