    Hello, ladies and gentlemen, it gives me a great honor to introduce our speaker for today’s lecture, Dr. Thomas Wood. Dr. Wood, professor of sociology at University of California, has written numerous articles and books on the topic of interpersonal relationship, which troubles most people nowadays. Welcome, Dr. Wood.   
    Dr. Wood:      
    I have heard lots of complaints from friends that they feel unsafe and upset about everyday life—a difficult relationship, a stressful lifestyle, a fast pace of life and some tough situations to deal with. Before I give my reply, I just think about it for a while. What’s the source of so much unhappiness?
    What sounds or impressions are you making on the people around you? Think about it. Your words, phrases, even your message may soon be forgotten but believe me, good or bad, your melody lingers.
    An odd choice of phrase? Not really. The dictionary defines melody as a succession of sounds, and what is life other than the combining and blending of a succession of movements and sounds.
    Just as a musical composition affects the moods and emotions of people who hear it, so does the way you live your life.
    Think of your life as a blank sheet of manuscript paper. Only the rhythm is there—it is up to you to create the harmony. Naturally you will want your composition to be a success, a chartbuster, even a symphony—something to be remembered with pleasure.
    So where to begin?
    You must begin with yourself. Have the right attitude, enjoy life, and most importantly, be optimistic about the future. Be genuinely interested in other people. Make a conscience effort to bring peace and happiness into other people’s lives. Avoid situations that generate excessive ambition, envy, anger and pride. They are all enemies of peace and will ruin your harmony.
    It has been said that if these emotions or feelings were banished, the world would live in perpetual peace. Well, to banish them from the world is probably aiming a bit high but it shouldn’t be too difficult to rid your own life of them.  
    Develop traits such as tact, diplomacy, compassion and sensitivity. These attributes are invaluable in enhancing not only your own life but the lives of those around you. Everything you do has an effect on those around you. The way you move, whether you smile or frown. You are capable of making someone’s day bright or miserable. Take time to listen to other people. If there are too many discords and not enough harmony in their lives, encourage them to have a brighter outlook.
    Throughout the world most people are striving for peace. From the family unit seated around the dinner table to world leaders at the conference table, the name of the game is the pursuit of peace. So, let us all play our part in composing the rhythm of life by consciously choosing peace and harmony in our daily lives to create a harmonious universe.
    If one of the suggestions I give you today is helpful to you in the future, I will feel really happy for giving you this speech. Thank you very much!
