  The Importance of Keeping Optimistic

Honourable judges, ladies and gentlemen,

Good afternoon! Today I would like to talk about the importance of

keeping optimistic。
   When we encounter difficulties in life, we notice that

some of us choose to bury their heads in the sand。 Unfortunately, however,

this attitude will do you no good, because if you will have no courage

even to face them, how can you conquer them? Thus, be optimistic, ladies

and gentlemen, as it can give you confidence and help you see yourself

through the hard times, just as Winston Churchill once said, “An optimist

sees an opportunity in every calamity; a pessimist sees a calamity in

every opportunity。
  ”

Ladies and Gentlemen, keeping optimistic, you will be able to realize,

in spite of some hardship, there’s always hope waiting for you, which will

lead you to the ultimate success。
   Historically as well as currently, there

are too many optimists of this kind to enumerate。 You see, Thomas Edison

is optimistic; if not, the light of hope in his heart could not illuminate

the whole world。
   Alfred Nobel is optimistic; if not, the explosives and

the prestigious Nobel Prize would not have come into being。 And Lance

Armstrong is also optimistic; if not, the devil of cancer would have

devoured his life and the world would not see a 5-time winner of the Tour

De France。
  

A rose may be beautiful, or maybe not; that depends on your attitude

only, and so does success, so does life。
   Hindrances and difficulties do

exist, but if you are optimistic, then they are only episodes on your long

way to the throne of success; they are more bridges than obstacles! Now I

prefer to end my speech with the great British poet Shelley’s lines: “If

winter comes, can spring be far behind?” Thank you!。
