“Sometimes when you're at your most certain, that's when everything you know is wrong.”

“In a way, it's nice to know that there are Greek gods out there, because you have somebody to blame when things go wrong. For instance, when you're walking away from a bus that's just been attacked by monster hags and blown up by lightning, and it's raining on top of everything else, most people might think that's just really bad luck; when you're a half-blood, you understand that some devine force is really trying to mess up your day.”

“When everything is coming your way, you're in the wrong lane.”

“When you think you're right, you're most likely wrong.”

“This was when I learned that you have to give up your life as you know it to get a new one: that sometimes you need to let go of everything you're clinging to and start over, whether because you've outgrown it or because it's not working anymore, or because it was wrong for you in the first place.”

“The beginning of wisdom, as they say. When you're seventeen you know everything. When you're twenty-seven if you still know everything you're still seventeen.”
