qqp question1: I've been learning piano since I was 12 years old. I'm 18 now and I still suck at piano. I did stop piano for 1-2 years in between, but I still suck at playing it. I have my grade 4 certificate. How am I supposed to play like a pro pianist? question2: I've played piano for 11 years and violin for 5 years. If I spend 1 hour a day learning cello, how much can I learn in 2 months?
