“Maybe we spend most of our decades being someone else, avoiding ourselves, maybe a man is only himself, his true self, for a few days in his entire life.”

“When it happens, this is what happens: I shoot myself.Not, you know, my self self. I shoot my future self. He steps out of a time machine, introduces himself as Charles Yu. What else am I supposed to do? I kill him. I kill my own future.”

“How do you convince someone to change, to stop being afraid of himself? How do you convince yourself not to be so scared all the time?”

“The only free man," he would say, "is one who doesn't work for anyone else.”

“I was headed for an entire life spent alone, pitying myself for not being more, ignoring all those people who actually ask me to be more, because they see it in me.”

“The path of a man's life is straight, straight, straight, until the moment when it isn't anymore, and after that it begins to meander around aimlessly, and then get tangled, and then at some point the path gets so confusing that the man's ability to move around in time, his device for conveyance, his memory of what he loves, the engine that moves him forward, it can break, and he can get permanently stuck in his own history.”

“Who do you imagine you are? Imagine there's a version of you that sees all of it. A version that knows when versions are messing with the other ones, trying to get things off track, trying to erase things. A record of all the versions, partial and deleted and written over. All the changes. All truths about all parts of our self. We break ourselves up into parts. To lie to ourselves, to hide things from ourselves. You are not you. You are not what you think you are. You are bigger than you think. More complicated than you think. You are the only version of you that is you. There are less of you than you think, and more. There are a million versions of you, half a trillion. One for every particle, every quantum coin flip. Imagine this uncountable number of yous. You don't always have your own best interests at heart. It's true. You are your own best friend and your own worst enemy. . . . Only you know what you need to do. Imagine there is a perfect version of you. Out of all the oceans of oceans of you, there is exactly one who is perfectly you. And that's me. And I'm telling you that you are the only you.”
