"I grew up playing the guitar. I started when I was nine, and by the time I was nine and a half or ten, I was doing seven or eight hours' practice every day. I did two hours' practice at six o'clock in the morning before I went to school, and another two hours as soon as I got home from school in the afternoon. Then I did four hours at night before I went to bed. I did that until I was fourteen or fifteen."
