“Before forty, you think that exhaustion is something like a long-lasting hangover. But at forty you learn all about it. Even your passions exhaust you.”

“It was like being given a maths problem when your brain's exhausted, and you know there's some far-off solution, but you can't work up the energy even to give it a go. Something in me just gave up.”

“Freedom from obsession is not about something you do; it's about knowing who you are. It's about recognizing what sustains you and what exhausts you. What you love and what you think you love because you believe you can't have it. (p. 163)”

“I can’t wait to find out how you taste, and you won’t want me to stop even after I’ve completely exhausted you. You’ll think you were on fire, your skin will burn. I’ll suck all of your juices out of you. And then I’ll drink your blood.”

“Kit, you're forty. You look thirty. You act...well, never mind. You're carrying on like you think you're seventy”

“Exhaust your worries and they will soon leave you.”
