演講原文如下：Ladies and Gentlemen：

    How well are we in tune with the rhythm of life ？ In our busy day
to day existence， we don ‘t often stop to ask ourselves this question.
At least I don’t. And it wasn‘t until I joined a competitive sporting
event that I learned a most important lesson– we must place our mind
in harmony with the natural order of things to be successful.

    Let me tell you what happened.

    I decided to take part in an International Marathon in my hometown
last year. Being an ambitious person， I hoped to finish it within 5 hours，
accompanied by my friend with whom I had trained.

    The big day finally arrived.“Ready ……set ……bang” And we were
off.

    At first， we kept a rapid pace and ran nonstop. At this pace ， we
finished the first 20 kilometers in 2 hours and I thought running a marathon
was a piece of cake. Then my running mate began to slow down. I urged
him to keep running at the same pace but he said no ， he wanted to conserve
his energy. I felt I had partnered with the wrong person， therefore，
I sprinted on and left him behind in the dust.

    A few kilometers later， I began to understand his strategy as my
pace slowed to a jog then a walk. After that I was incapable of moving
another step. I was humiliated as more and more people ran passed me.
More than once I thought“Maybe I should quit.” I started to doubt my
ability to finish this race.

    At this moment， my running mate caught up with me and slapped me
on the back.“Follow me ，” he shouted. He had balanced his marathon
pace and was encouraged me to do the same. For the rest of this grueling
contest ， we walked， jogged ， ran a few miles， and walked again. Slowly，
painfully but hopefully this time ， we established the most suitable
pace within the natural flow of our physical capabilities.

    Eventually we accomplished our first Marathon of 42 kilometers in
4 and half hours. I asked myself， what did this marathon mean to me？

    My Marathon experience became an influential metaphor for my life
about how we must learn to pace ourselves in everything ， by being in
tune with the rhythm of life.

    Like the tide that ebbs and flows ， we must listen to advice but
make our own decisions. Like the show at dawn and dusk， we must learn
to balance pride and modesty. And from the way the wind can both shout
and whisper ， we must learn when to be strong and when to be gentle，
for everything moves in its own rhythm and its own yin and yang elements.
It is the interaction of these complementary extremes that produces harmony，
as Laozi said ， extremes meet. Since the marathon， this notion of two
opposite forces working together has been my running partner， so to speak.
Yin and yang exist everywhere ， constantly interacting ， and never existing
in an absolute condition.

    Ladies and Gentlemen， life is like running a marathon， let us discover，
define and develop a natural rhythm of life ， in order to achieve both
harmony and success.

    Thank you for listening.
