Now that I'm almost forty, I look back at some of the decisions I made when I was younger - decisions that I thought of as courageous, or generous, or otherwise befitting a writer; befitting someone who had taken it as their life's goal to understand the human condition - and I wish I could go back in time and be like, "Hey, you don't actually have to do that - you're allowed to look out for yourself a little bit."

People are shaped by friendship as much as by romance.

When a novelist manages to describe or evoke something you thought or felt, without realizing that other people also found themselves in the same situation and had the same feelings, it creates that same solidarity. Maybe it's better to think of humor not as a tool to express the solidarity, but a kind of by-product. Maybe the realization "I'm not on my own on this one" is always, or often, funny.

Humor is really important to me. All my favorite writers are writers I consider to be funny, including Tolstoy and Dostoevsky, even though that's not necessarily their rap.

If you're writing a book where you want to make a positive truth claim, then you should absolutely call it nonfiction or memoir. If you don't want to make that claim - if that's not what's important to you; if you're more interested in storytelling and interiority and interpersonal relationships than in objective, checkable facts about the world - then why wouldn't you call it a novel, and take advantage of what that gets you, of the extra freedom, of belonging to the tradition of the novel?

There's an amazing line in Marcus Aurelius: "The healthy eye ought to see all visible things and not to say, I wish for green things; for this is the condition of a diseased eye." Maybe green is your favorite color - but if you saw everything as green, that wouldn't be a blessing, it would be an eye disease. By the same token, if there was no heartbreak, and everything happened exactly as you want - it would be a less beautiful and meaningful story than the actual story, where you're a part of a huge complicated mysterious whole.

If you think about Don Quixote, Don Quixote is this guy who wants to live as if he was in a medieval chivalric romance, when actually he lives in sixteenth-century Spain, which is already going through secularization, industrialization, modernization. He goes out to kill a giant, and instead he collides with this huge windmill and injures himself and also damages the windmill. I think that's a metaphor for the collisions we all have over time, as our ideas of ourselves get out of synch with the historical moment.
