Booking Through Thursday (18) - Quotable

A weekly meme about (mostly) books and reading.
The BTT question of the week is:

Valentina asks:

Do you have a favorite quote from a book?

I have a lot of favorite quotes from books that I think it's quite impossible to write them all down here. Well, it is possible, however, a long post is quite a... bit not only for the writer but also for the reader; therefore, I'm going to share only five favorite quotes from books that I've read recently.

1. "Going backward and admitting defeat is more difficult than continuing forward, no matter how pointless the journey." - Ordained by Devon Ashley

2. "Nobody else will ever be able to save me if I'm not fighting as hard as I can to save myself." - Fateful by Claudia Gray

3. "Cruelty does not make a person dishonest, the same way bravery does not make a person kind." - Insurgent by Veronica Roth

4. "People, I have discovered, are layers and layers of secrets. You believe you know them, that you understand them, but their motives are always hidden from you, buried in their own hearts. You will never know them, but sometimes you decide to trust them." - Insurgent by Veronica Roth

5. "Why is it that anytime somethin's different, it's automatically wrong?" - Grey Eyes by Brandon Alston and Quinteria Ramey

How about you? What are some book quotes that had inspired you?
