Kindness comes in many forms. From larger, purposeful acts such as volunteering to smaller acts such as striking up a conversation with neighbors new to the block. Kindness can be more than a warm feeling—it can be a meaningful lifestyle that can have a transformative impact on all areas of our lives. This special edition from the editors of TIME delves into the concept and practice of kindness. Kindness is teachable and attainable, but why are we kind? Why are some people kinder than others? And why does kindness matter. Highlights include: How kindness can lead to a more successful life, teaching your kids to be kind, the art of being kind to yourself, the science of kindness and much more.
