    Hello, ladies and gentlemen. It is my honour to introduce our keynote speaker for today’s lecture, Gretchen Rubin. Ms. Rubin received international attention for her 2009 best-selling book, The Happiness Project, in which she re-examines her own happiness and tries to develop mood-boosting habits. Today, Rubin will share with us her mood-boosting experience. Welcome, Ms. Rubin. Ms. Rubin:
    Good afternoon, everyone. Before I elaborate, I’d like to first brief some of my most effective mood-boosting tips. For the most part, they can be accomplished in a minute or less.
    1. MAKE YOUR BED
    The thing that’s surprising to me is that, for most people, outer order does contribute to inner calm and creativity. One easy way to maintain order and, in turn, boost happiness, is to make the bed, every day.
    2. SMELL THE ROSES—OR SOMETHING ELSE NICE
    I used to laugh at scented candles but now I understand scents are a way to get a quick lift without any time, energy and money.
    3. FOLLOW THE "ONE-MINUTE RULE"
    Overwhelmed by unopened mail, and other tiny tasks? The one-minute rule says that anything I can do in less than a minute, I should do without delay. So I don’t postpone hanging up my coat, printing out a document and filing it, glancing over a letter and throwing it away.
    4. SET AN ALARM—AND NOT JUST FOR WAKING UP
    Since sleep and mood are linked, I think folks who struggle with turning out the light may benefit from a bedtime alarm. For many people, an alarm really helps; they just need that trigger.
    5. DON’T LIKE A BOOK? STOP READING IT
    I mean, I don’t watch a TV show if I don’t like it. So why not apply the same logic to books? I used to have this feeling that a "real reader" would finish a book if he started it. Now I just have so much more time to read the books that I like, and I love everything that I read.
    6. TAKE ONE THING WITH YOU
    This one may be especially helpful for parents: When leaving a room, pick up as you go, one thing at a time, without having to dedicate a lot of time and energy to it.
    7. LISTEN TO AN UPBEAT SONG
    It’s familiar, but it actually does work. It’s a very easy way to change your mood.
    8. JUMP UP AND DOWN
    I strongly recommend this simple energy-booster, especially when you may only have a few seconds to spare.
    9. KISS SOMEONE YOU LOVE
    Ancient philosophers and contemporary scientists would agree that relationships are a key—maybe the key—to happiness. So anytime you do something that broadens your relationships or deepens your relationship, it’s going to make you happier.
    10. MAKE SOME "BRIGHT-LINE RULES"
    I believe habits have a direct connection with happiness, and I think hard rules can spare one the agony of decision-making. Now, I will explain these tips one by one in details…
    16. Which of the following is a mood-boosting habit according to Rubin?
    17. What is "ONE-MINUTE RULE" according to the lecturer?
