" That’s why I liked the Suzuki method of teaching piano. There are seven books, and everybody has to start with Book One. Each book includes ten to fifteen songs, and you have to go in order. Kids who practice hard get assigned new songs each week, whereas kids who don’t practice get stuck on the same song for weeks, even months, and sometimes just quit because they’re bored out of their minds.
