You have a pet theory, one you have been turning over for years, that life itself is a kind of Rube Goldberg device, an extremely complicated machine designed to carry out the extremely simple task of constructing your soul.

I write out of gratitude for all the books I have loved over the years.

Anyone who has ever experienced love knows that you can have too much or too little. You can have love that parches, love that defeats. You can have love measured out in the wrong proportions. It's like your sunlight and water - the wrong kind of love is just as likely to stifle hope as it is to nourish it.

The books you love best - those are the immensity of the sea.

How often, you wonder, has the direction of your life been shaped by such misunderstandings? How many opportunities have you been denied--or, for that matter, awarded--because someone failed to see you properly? How many friends have you lost, how many have you gained, because they glimpsed some element of your personality that shone through for only an instant, and in circumstances you could never reproduce? An illusion of water shimmering at the far bend of a highway.

I had always been the kind of boy who was quick to laugh and quick to cry.

You could not presume that people were healthy. You could not presume that they would welcome the little nudges and jostlings of life. You had to behave as though everyone you met was walking a thin wire far above the earth, where the slightest wind might rock them off their balance and send them tumbling to the ground.
