I've a performance certificate from Berklee College of Music, Boston MA (woodwinds, composition). I played professionally for 10 years, then went back and did a B.Ed, M.Ed, and Ed.D in music and English (double majors) with a minor in statistics at the masters and doctoral levels. I spent 20 years teaching high school: 10 in music and 10 in computer science. Then taught at university and simultaneously ran my own IT company specializing in networking (this was in the 90's so networking was in its infancy!) and am now happily retired! But if you want advice, I'm a teacher - I love to tell people what they should do.
