Nasreen of Information Services recommends The Happiness Advantage by Shawn Achor:
The Happiness Advantage turns our basic assumptions of happiness upside down. We assume that if we work hard, we will be successful. If we’re successful, then we will be happy. This book summarizes the research that teaches us that we must first be happy, then success comes and this happiness fuels our motivation and gives us the competitive edge which is the Happiness Advantage.
Happiness comes from a positive attitude towards life and the most important emotion that brings happiness is gratefulness. Gratefulness for your situation in life naturally results in happiness. The Happiness Advantage can be applied not just to yourself but to your relationships and leadership roles in schools, churches, volunteer organizations and other businesses.
