Piano

Ughh!!!  There is this song I really want to play on the piano (A River Flows in You by Yiruma) but one problem: I don't know how to  actually read piano music!!!  I tried learning before but then I got bored so I quit.  OK... possible solutions: 1) learn to play piano again. why that won't work: my parents probably won't pay for it again. Plus, it's going to take a long time for me to get good enough to play that song. 2) ask my best friends who play piano to teach me that one song. why that won't work: it's a very long song... I can't memorize it. 3) try to teach myself. why that won't work: I don't know what all the signs mean and I can't read the music.  Bottom line: I HAVE A LOT OF WORK TO DO!!!
