A practical, approachable guide that reduces complex feelings to simple "equations"—pairings of causes and modifiers—that make emotions easier to name, analyze, and shift; using hospitality-industry stories and personal anecdotes, it offers formulas (for example, despair as pain minus hope) along with concrete practices—reframing, gratitude, connection, meaning, and learning—to help readers transform negative states, cultivate resilience and purpose, and apply emotional insight in work and everyday life.
