“Believe it or not -- it takes a lot of love to hate you like this.”
I Am The Messenger - Markus Zusak
I don't know if I can exactly say it changed my opinion but it definitely made me aware of how much small deeds and strangers can impact your life, for better or worse, and how much one can actually achieve through these small deeds, despite their opinions of themselves and of their place in the universe.
It's a magnificent book, really.
