    Hello, ladies and gentlemen. It gives me great pleasure to introduce our keynote speaker for today’s session, Dr. Bill Green. Dr. Green, professor of human resources at Harvard University, has written numerous articles and books about how to spend your college life more meaningfully and get prepared for your future career. Welcome, Dr. Green.
    Dr. Green:            
    Thanks for the introduction. The first year of college is one of the best and the most interesting periods of life. You should be strong enough to step into the next stage of your life without doubt and hesitation. On the one hand, it can be stressing to leave your town and start communicating with the people you don’t know, but when you get used to the atmosphere, you’ll really appreciate and love the time spent in college.
    You should find time to reflect on yourself and realize what really interests you. Take responsibility for yourself and choose the list of majors you want to study. Sure, you have the right to change the majors during the course of your college career, but it’s desirable to make a right decision faster. If you’re not sure what subjects to choose, then try to visit a couple of classes in order to understand what is better for you.
    As far as I know, every respected college has a range of student programs, competitions and part-time campus jobs. So, one of the hardest things to do is to organize a student’s life. I want you to know that the most important thing to do is to find the balance in various activities of your life. It’s very difficult to deal with different subjects and students’ organizations at the same time. First of all, you need to learn how to manage your time, because it is a key component to academic success. Then you’ll be able to organize your study, social and private life.
    Nowadays all college campuses offer you a big variety of student organizations. Different social and sport organizations can help you express yourself and discover your interests. As a student, the first course you need is to make friends and get involved in different student communities. Your membership will improve your reputation in college and fill your busy student’s life with new emotions and adventures.
    Your study at college can be tough, but this period of life is the most colorful. During your study, you develop your personality and meet new friends. Moreover, you can have fun, fall in love and enjoy the greatest four years of your life.      
    I hope this speech will rid you of all fears which keep you anxious about your first year. You need to remember that you are the only one who’s responsible for your study. That’s why you should learn how to manage your time and balance both college and private life.
    Thank you!
