I buy a one-off; I see a book someone will like and I buy that. I have bought Bird by Bird by Anne Lamott for a number of people who’ve told me they were struggling with writing, because I think it’s a really great writing book and it’s a good read anyway.

There’s one book I’ve given the most in my life, which is a book called – well, there are several now that I think about it. There’s a book by Timothy Wilson called Strangers to Ourselves , which is one of the loveliest, most insightful books about social psychology that I ever read. And I give that a lot to people. And every time I meet, and really, I’m always meeting people who work in retail, particularly I always send them, particularly if they’re Jewish, I send them a book called The Merchant Princes . It’s a book about the great Jewish retail families of America. So in the 19th century, all of these people come over from Europe who have experience in the garment trade or retailing. And an extraordinary number of the early 20th century/late 19th century department stores pop up around America are founded by Jewish immigrants from Europe from, literally, you go to any town in America, the traditional department store is from one of those families. Well, a guy, and I’ve forgotten his name, wrote a book about those families, and it’s called The Merchant Princes , and it’s fantastic.

Yeah, well, I love poetry and it’s almost cliche now to say this because so many people like his work, but I think David Whyte’s work is just beautiful and is a wonderful kind of entry point to poetry. I’m also a big Wendell Berry fan. He’s written a lot about farming and the natural world. And I’ve never met him, but I’m a huge Wendell Berry fan. I’ll sometimes give Wendell Berry books as gifts. The book that I think is perhaps, at least to me, the most beautiful book of all is Longitude by Dava Sobel about the history of the discovery of timekeeping at-ocean, which is not a trivial problem to solve. And it’s just a beautiful story of how scientists, or in this case a particular scientist, merged the quest for a technology with a scientific problem with adventure, and going out on boats and risking one’s life for the sake of science is something that resonates with me a bit. And it’s a beautiful, short book, and it’s very accessible to anybody, whether or not you have a background in science or not, and she’s absolutely a wonderful writer. And so that’s the one I gift most often.

Ever since adolescence, [my elder sister Anna] has been an enthusiastic admirer of the great Swedish writer, the Nobel Laureate Selma Lagerlöf, and she infected me so much with her enthusiasm that I decided to become a writer and describe Italian saga "à la Lagerlöf". But things were to take a different turn.

I have a very peculiar answer. Really, really amazing nail clippers. Pay 50 bucks for them, or something. It could change your life, I promise.
