Hi, chopin_rules, its never too late to start a career in music. I personally started learning piano when I was 17 years old and I am now 20 years old now, and I am going to make music my career, you have much more headstart than me. At my age it is much harder to realise my goals than you. Anyway, you are doing fine, just keep on progressing like you now and in 3 or 4 years get into a good music college and let things take its course. Anyway, one advice, if you are thinking of becoming a very good performer, prepare yourself for a lifelong of learning and discipline in piano playing.
