That's why I always dread the initial phrase and don't practice my piano at all. Its only until I know my exam is coming will I force myself to learn the piece. And once I get the hang of it, I can play the same piece for 3 to 4 hours without end.
But I can only imagine how my family felt when I first start learning a piece every single time. Can you imagine having stainless steel drums in the house? Oh god.. I really hope my future son/daughter/husband is not gonna be a drummer. If he/she is going to be one, make sure there's gonna be a sound proof room in the house.
Please please please.
