This book delves into the art of happiness. It is shown that it is easy to choose to be happy. The difficult part is how to live life happily in spite of almost everything in life that conspires and threatens to unleash misery and discontent. Happiness is a state of mind that those with the right skills and attitude can somewhat control. Three positive healing C words summarize the positive state of mind that everyone should aim to have: Cheerful, Considerate, and Collaborative.

On the other hand, bloodymindedness, selfishness and anger are the three worst emotions of human beings. They are responsible for all the terrible things that happen in life. They are the greatest killers of happiness. The book explains comprehensively how actively managing these three positive and three negative elements of life is so important in achieving happiness in life.
