I'm limitless, spontaneous and fearless. I can take direction and also give it. And I don't dwell on celebrity.

I write by myself and then deliver the song. Everybody knows, 'Leave Ester alone when she's in her zone.' Give me a studio and the tracks, and I'll call you when the doctor is done.

I see what other people do and what songwriters don't. They don't get out and take care of themselves. Producers turn themselves into a massive brand. Songwriters tend to be under someone else's umbrella. If you're building your own legacy, it can't be under an umbrella.

I'm universal. As much as I can get out a 'Firework' with Katy, I can get a 'Lil Freak' out with Usher. Or a 'Lay It Down' with Lloyd. I can get Caribbean as I did on 'Rio,' then go from there to working with No Doubt.

I will make up a crush, you hear me?! I will look at a guy and say, for two months at least, 'I think you're cute.' And then I can be psycho. I will go in my head and make a whole life with him, he don't even understand why I'm mad at him. I'm like... 'cause you came in late last night!' And he's like, 'I don't even know you.'

I can't change the direction of the wind, but I can adjust my sails to always reach my destination.
