From Brené Brown's Atlas of the Heart, which systematically explores a wide range of human emotions and experiences. The source is structured into chapters focusing on different categories of feelings, such as those related to unfulfilled plans, confusion, pain, and connection with others. It blends personal anecdotes from the author's life, including experiences with decluttering and family dynamics, with extensive social science research to provide nuanced definitions of complex feelings like vulnerability, shame, anxiety, dread, and the distinctions between envy and jealousy. Ultimately, the work champions emotional literacy and self-awareness as essential prerequisites for cultivating meaningful connection and grounded confidence.
