“Have you ever truly, keenly felt like you don't know who you are? Do you ever do something and think, Who is at the controls? Like some mad pilot has locked you out of the cockpit? I definitely do. I feel a kind of vertigo that makes me shake afterwards. I guess we all feel it when making a difficult-seeming choice, and sometimes you seriously don't know what you want because you don't know who you're supposed to be, or who you want to be. Physics, my first and second families, my philosophy degree, had all failed to help me answer that question. The former has led me to wonder whether I am one of an infinite number of Alices in multiple universes. A quantum fuck-up, which is someone who fucks up in every one of those universes but in different ways.”
