At some point, those cool haircuts, sneakers, and skinny jeans are not age-appropriate. Besides, you don’t want to look at a picture of yourself 10 years from now where you’re emaciated because that was the trend.

There are better ways of looking good than focusing on one wrinkle. And the sum total of plastic surgery can be so frightening when every part is done. You’re like a patchwork, and that’s far worse than just looking old.

If you can, splurge on a beautifully tailored cashmere coat. Put it on over jeans and a T-shirt and you’re done. But in the winter you can also leave the coat at home and just wear a beautiful scarf with your suit.

There are fragrances you just remember and marry to people. I’ve always loved that. A signature scent is a beautiful and unique way to leave a lasting impression.

Gifts given for no reason are always appreciated. If you have a list of 50 people to buy for during the holidays, it’s not pleasurable for you or them.

There’s a wonderful thing that happens to a white collared shirt when it’s steam-cleaned and pressed. Somehow it becomes better than when you bought it.

There’s no delicate way to tell a woman that you don’t like what she’s wearing. You’re fucked.
