The goal is to be both disciplined and loose, so that the writing does not turn into a task or a chore. To leave myself behind, along with the mechanics, and disappear into the lives of my characters.

Just like that. Gone forever. They will not grow old together. They will never live on a beach by the sea, their hair turned white, dancing in a living room to Billie Holiday or Nat Cole. They will not enter a New York club at midnight and show the poor hip-hop fools how to dance. They will not chuckle together over the endless folly of the world, its vanities and stupid ambitions. They will not hug each other in any chilly New York dawn. Oh, Mary Lou. My baby. My love.

In the end, the only thing the true New Yorker knows about New York is that it is unknowable.

What libraries give you is all three tenses - the past tense - the present tense in which we live and the future that we can only imagine. These places have teachers who are living and dead and we are lucky to have them. If I sit here and read Aristotle, he is speaking to me across a thousand years - more than a thousand years. That sense that I am in the company of the great greatest people who ever lived is a humbling experience but a liberating experience.

My ambition was to embrace those general qualities that Ernest Hemingway, a former newspaperman, once said should be present in all good books: 'the good and the bad, the ecstasy, the remorse and sorrow, the people and the places and how the weather was.'

There are 10,000 books in my library, and it will keep growing until I die. This has exasperated my daughters, amused my friends and baffled my accountant. If I had not picked up this habit in the library long ago, I would have more money in the bank today; I would not be richer.
