Luckily, he loves a wide array of music, so it's not like his only goal is to be a rock star (NTTIAWWT), and I can see him writing music (the area I'm trying to nudge him towards right now), but he's great with people and it wouldn't be too shabby being able to introduce him as "this is our son, the Dr." one day. ;-)

Music is fun now and should be but people who make a living at it work as hard at that as a scientist in a lab and most of the work is dull, repetitive and boring."
