Self-compassion is the practice of treating yourself with the same kindness and understanding you would offer a good friend who is suffering. Kristin Neff, the leading researcher in the field, identifies three components: self-kindness (warmth toward yourself in moments of failure), common humanity (recognizing suffering as a shared human experience rather than a sign of personal inadequacy), and mindfulness (holding painful feelings in balanced awareness rather than over-identifying with them). Research shows that self-compassion is a stronger predictor of emotional resilience than self-esteem — and unlike self-esteem, it doesn't require you to feel superior to others or succeed at everything.
