“All you imagined, no matter how wild it might seem, was no more than a disguised version of what you already knew.”

“Be what you would seem to be - or, if you'd like it put more simply - never imagine yourself not to be otherwise than what it might appear to others that what you were or might have been was not otherwise than what you had been would have appeared to them to be otherwise.”

“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.”
