Happiness is a skill, not a lucky break. Our happiness is not under the control of others. We can learn how to make ourselves happy. Recognition of this fact is highly empowering. 
 
Happiness levels are not significantly different based solely on sex, race, or age. Demographic factors do not have a substantial impact on a person’s reported level of happiness, supporting the idea that happiness is largely influenced by other factors, such as individual mindset and circumstances. 
 
Why should you or your employer care if you are happy? Happy leaders get more done through their people. This is because people prefer to spend time with someone who is happy, and they avoid unhappy people. Leaders need time with people to influence their behaviour, which is what leadership is about. Who wants to follow a sourpuss? 
 
Therefore, the happier you are, the more people will want to spend time with you, giving you more opportunities to influence their behaviour. This book will help you become and stay happy, both in life and at work.
