Simple and succinct. We lie every day. Most of us have heard the majority of the arguments made in this book, but this one really hit home for me:

In fact, suspicion often grows on both sides of a lie: Research indicates that liars trust those they deceive less than they otherwise might—and the more damaging their lies, the less they trust, or even like, their victims. It seems that in protecting their egos, and interpreting their own behavior as justified, liars tend to deprecate the people they lie to. - Page 39
