I think Amanda had picked this one up during a deal at some point. I was trying to figure out what to read and browsing through the Kindle when I saw this. It sounded good, and I've had a leaning towards generosity lately, so it seemed right up my alley.
Lots of good examples in here, though some are only really particularly relevant if you live in an urban setting.
One thing that rather messed me up a bit was talking about your friendships and encouraging friendships outside of your typical social / economically-similar circles. Again, a really good idea, but I'm currently struggling to develop close friendships of any sort, even within my own "characteristics."
Ugh. I'm going to go donate some money now and hopefully feel a little bit better about myself...
