Learning and playing music requires focus, concentration, and discipline. If you can apply it to music, you can apply it to school and to work.

That said, I have serious doubts about the numbers. The number of young people who study music has gone down significantly over the years, but the number that go on to post-graduate studies has risen significantly. So I don't really see how 88% of them can have studied music, either in school or privately. And that business about 83% of people making $150,000 a year having a music education? How many people do you know with a music education that make $150,000 a year? Of course, the number of people who lie on surveys probably is probably a constant.
