I really enjoyed Brené Brown's book "The Gifts of Imperfection." These kinds of messages are crucial in our culture these days. Her connections between various virtues was great, and it's based on qualitative research. A lot of her research is on shame, its effects and shame resilience.
My first exposure to her was a couple of TED talks.
She has other books, and the next one I want to read is Daring Greatly.
