“It was possible, he understood, for a person's life to become just a long series of mistakes, and that the end, when it came, was just one more mistake in a chain of bad choices. The thing was, most of these mistakes were actually borrowed from other people. You took their bad ideas, and for whatever reason, made them your own.”

“It took me a long time to learn that mistakes aren't good or bad, they're just mistakes, and you clean them up and go on.”

“It is one thing to make a mistake, and quite another thing not to admit it. People will forgive mistakes, because mistakes are usually of the mind, mistakes of judgment. But people will not easily forgive the mistakes of the heart, the ill intention, the bad motives, the prideful justifying cover-up of the first mistake.”

“When it came down to it and the life-or-death decision had to be made, then it was made by you, because you were the witch. And sometimes it wasn't a decision between a good thing or a bad thing, but a decision between to bad things: no right choices, just... choices.”

“If a fight isn't a life or death situation - which honestly most aren't - people should realize people make mistakes, no one is perfect, and move on from it. For holding onto bad feelings just makes you bitter and makes you one day regret holding onto it when in the long run it most likely won't make a difference.”

“Some mistakes... Just have greater consequences than others. But you don't have to let the result of one mistake be the thing that defines you. You, Clark, have the choice not to let that happen.”
