Your shoes have to match your belt. That's rule number one for guys. You can't put the brown shoes with the black belt. Or a brown belt with a black wristwatch. Just don't do it! Also, I don't like boots with suits. And when you wear sneakers, make sure they go with your shirt.

I learned what a Birkin bag is from the price tag. You'll never forget what it is once you've paid for one.

Leapfrog innovation - consistent, constant, ridiculous leapfrog innovation - only happens within a dictatorship.

I don't understand shopping, it doesn't make any sense to me. As guys, we decide we want something and then we go out and buy it.

I don't get it.

I think great relationships are great partnerships, and those come in all shapes, sizes, forms, ages. The only tip I have for anyone in a relationship or a partnership is work on it when it's good. It's very easy to try to take the break when things are going good, but that's the time you have to keep working on it, because you can keep it good, and that's worth a lot.
