Linda Kaplan Thaler and Robin Koval authored the book "The Power of Nice" which argues that being kind and considerate in business ("nice") leads to greater success than traditionally aggressive strategies. The book outlines six principles of the power of nice, including planting positive seeds through small kind acts that can grow relationships over time, and avoiding negative impressions that infect your reputation. Overall, the book shows that nice companies have lower costs, happier employees, and nice people themselves live longer, healthier lives and earn more money in today's interconnected world.
