1. You can’t read them.
As a group they’ve mastered the skill of being quiet and obedient no matter how insane the adults around them. As a result, you can’t tell what exactly they’re thinking at work. No matter what, they’ll have you convinced that everything is fine until they quit.

…

3. They are overqualified.

When I think about kids watching a TV show like American Idol or The Voice, then they think, ‘Oh, OK, that’s how you become a musician, you stand in line for eight f****** hours with 800 people at a convention center and then you sing your heart out for someone and then they tell you it’s not f****** good enough.’ It’s destroying the next generation of musicians! Musicians should go to a yard sale and buy an old f****** drum set and get in their garage and just suck. No two people play the same. Even if you’re playing the same song on the same instrument as somebody else, you will play it differently because you are you. And that’s a good thing! All of your imperfections and all of your bad habits give you your own sound and style. Music’s not meant to be perfect. It’s meant to sound like the way you do it. When you put human beings together with other human beings to make music you get magic.
