What did thinking ever do for me?

I never thought about things at all, everything changed, the distance that wedged itself between me and my happiness wasn’t the world, it wasn’t the bombs or burning buildings, it was me, my thinking, the cancer of never letting go, is ignorance bliss, I don’t know, but it’s so painful to think, and tell me, what did thinking ever do for me, to what great place did thinking ever bring me? I think and think and think, I’ve thought myself out of happiness one million times, but never once into it.
(Jonathan Safran Foer – Extremely Loud and Incredibly Close)
