I travel so much and am always living out of a suitcase, so my favorite saying is 'Wherever you go, there you are'. I love it because it's reassuring to me that you have to live in the moment wherever you happen to be.

I love Rebel Rebel in Manhattan's West Village for vinyl, but record stores are hard to come by these days. I almost don't even use iTunes. I mostly use music subscription services. But I'll go into Rebel Rebel once a month or so and buy everything I love on vinyl.

I'm such a fitness freak that I eat so plain, it's gross. I have oatmeal in the morning and then I have chicken breasts and vegetables and spinach shakes.
