This book is not written for experts, nor is it written for those who treat real problems as mere gossip. You will not find profound philosophical principles or difficult erudition in the following chapters.My purpose is simply to collect here some comments through the perception of what I hope are ordinary things.All the tips that I advocate and offer to the reader are based on my experiences and observations, and they enhance my happiness whenever I act on them.For this reason, I venture to hope that the many men and women who suffer from misfortune rather than happiness will diagnose their symptoms and find a way out of them.I believe that through my efforts in this book, many unhappy people will become happy and sweet.
