“My father makes to-do lists, makes plans, makes business plans. This is how he starts, always with a blank sheet of graph paper.”

“Look at that," he said. "How the ink bleeds." He loved the way it looked, to write on a thick pillow of the pad, the way the thicker width of paper underneath was softer and allowed for a more cushiony interface between pen and surface, which meant more time the two would be in contact for any given point, allowing the fiber of the paper to pull, through capillary action, more ink from the pen, more ink, which meant more evenness of ink, a thicker, more even line, a line with character, with solidity. The pad, all those ninety-nine sheets underneath him, the hundred, the even number, ten to the second power, the exponent, the clean block of planes, the space-time, really, represented by that pad, all of the possible drawings, graphs, curves, relationships, all of the answers, questions, mysteries, all of the problems solvable in that space, in those sheets, in those squares.”

“There must be some kind of internal time distortion effect in here, because when I look at myself in the little mirror above my sink, what I see is my father's face, my face turning into his. I am beginning to feel how the man looked, especially how he looked on those nights he came home so tired he couldn't even make it through dinner without nodding off, sitting there with his bowl of soup cooling in front of him, a rich pork-and-winter-melon-saturated broth that, moment by moment, was losing - or giving up - its tiny quantum of heat into the vast average temperature of the universe.”

“My father built a time machine and then he spent his whole life trying to figure out how to use it to get more time. He spent all the time he had with us thinking about how he wished he had more time, if he could only have more time.”

“There is a sense in which I am pretty sure this makes no sense. I don't know where this is going. I don't know how it ends.”

“This, then, is my choice:I can allow the events of my life to happen to me.Or I can take those very same actions and make them my own. I can live in my own present, risk failure, be assured of failure.”

“I know none of this seems very believable. It probably doesn't even make sense. But for once in your life, please, I am asking you to trust me. Trust yourself.”
