Anyone interested in the world generally can't help being interested in young adult culture - in the music, the bands, the books, the fashions, and the way in which the young adult community develops its own language.
I was at school when Britney Spears' 'Baby One More Time' came out. I changed my uniform to look like hers. I just looked slutty after that, so thank you, Britney.
People can live without a Facebook account: my 13-year-old daughter has cancelled her account because it's not cool anymore.
My aesthetic is probably closer to a 15-year-old's than my dad's, but I get his conviction.
Having a thirteen-year-old in the family is like having a general-admission ticket to the movies, radio and TV. You get to understand that the glittering new arts of our civilization are directed to the teen-agers, and by their suffrage they stand or fall.
I'm interested in Internet cultures. I'm interested in what the teenagers who drive the Internet culture are passionate about. I follow their lead - they go to tumblr, I go to tumblr.
Whenever teenage girls and corporate CEOs covet the same new technology, something extraordinary is happening.
I always say that teenagers are the first to know if you're pandering to them.
I love fashion. I shop like a 16-year old girl. Sneakers. That's what I spend money I don't have on.
In Japan, Australia, and England there is such a strong youth culture.
I bought a lot of rubbish things that kids buy: skateboards and clothes and typical teenage stuff.
Trying to tart the rock business up a bit is getting nearer to what the kids themselves are like, because what I find, if you want to talk in the terms of rock, a lot depends on sensationalism and the kids are a lot more sensational than the stars themselves.
In high school, everybody rapped. You just pounded on the table.
As long as there are teenage girls, there will be boy bands. It's a question of how long it takes them to get their music together to come out.
