Book excerpt: If "Who am I?" is the question you're asking, Rachel Jankovic doesn't want you to "find yourself" or "follow your heart." Those lies are nothing to the confidence, freedom, and clarity of purpose that come with knowing what is actually essential about you. And the answer to that question is at once less and more than what you are hoping for. Christians love the idea that self-expression is the essence of a beautiful person, but that's a lie, too. With trademark humor and no nonsense practicality, Rachel Jankovic explains the fake story of the Self, starting with the inventions of a supremely ugly man named Sartre (rhymes with "blart"). And we--men and women, young and old--have bought his lie of the Best Self, with terrible results. Thankfully, that's not the end of our story, You Who: Why You Matter and How to Deal with It takes the identity question into the nitty gritty details of everyday life. Here's the first clue: Stop looking inside, and start planting flags of everyday faithfulness. In Christianity, the self is always a tool and never a destination.
