It's cool to play the guitar, but to me it's even cooler to scratch a guitar backward and forward, to manipulate it with a turntable. Guitars can't do that themselves.

If kids can have some sort of social responsibility, that's cool. But if they're not actually having social responsibility, and they're kind of hiding behind it, that's kind of useless, or even worse.

You can't look forward and backward at the same time.

It's funny - some producers ask me, 'Man, how do you work on a Bieber record? That would kill my career.' I can work on any record there is as long as they are good records and you're pushing things forward.

When I worked with M.I.A., who was, like, the coolest person back then, she was just a girl I met on the Internet. Or even when I met Azealia Banks on Myspace, I never thought, 'Oh, she's cool.' I just loved what she was doing. So I've always been like that. And I think, as a producer, that's what you've gotta do.

Few tips,
Don't Stop, don't look backward, what has happen has already happen and try again.
