Science tells us that happiness is 50% genetic, 10% circumstantial, and 40% how we think and act—which leaves plenty of room to increase our happiness by adjusting how we think. For anyone wanting to increase their wellbeing, Deborah Smith shows how positive psychology—the science of happiness—can be used every day. Explaining key principles to provide the foundation for change, Smith offers questionnaires for measuring wellbeing and simple techniques that can easily be applied to a busy lifestyle. With case studies, anecdotes, and tips, this book provides a toolbox of positive principles and tactics for the ultimate self-care.
