What are you reading?

When is the last time you read something that really challenged you? I mean, seriously challenged you?

We tend to read things that resonate with us, don't we? We tend to appreciate input that backs up our own point of view. But when was the last time you read something--by choice--that wasn't like that? When was the last time you took in something that left you feeling sick in the pit of your stomach...because it disagreed with you...and you realized it was probably right?

Just food for thought. Get challenged. You may want to start here.
