What book had the greatest impact on your life, and which part of it is the most memorable for you?

Days of War, Nights of Love, by the Crimethinc Ex-Workers Collective.

I'm not gonna pretend I'm now some completely freegan anarchist living on the fringes of society or anything like that, but this book really opened my eyes up to what it means to live and the weight of making (or not making, more often) choices about how you live your life.

It was also the kick in the teeth I really needed at the time to finally break free from the (imo rather oppressive) religious structure I had grown up in. I think it would have happened eventually anyways, but it really did a great job of making for a good clean break, in a way where I really feel no lingering regret about it whatsoever (again, choosing how to live), other than maybe wishing it had happened sooner.

I just really wish I had kept in touch with the person that gave me the book in the first place.
