This was a very interesting story. I 1 thousands of classes since I started school nine
years ago. But one class was 2 of
all.
It happened last term just after I had got a bad result in 3 exam. I was sad and had lost my confidence. I decided
4 to a class 5 can tell me how to be successful. The speaker walked
into the room. 6 he
did not start talking like a teacher. Instead, he held up a twenty yuan note!
"Who wants this?" he asked. Unsurprisingly,
7 of us in the class held up our
hands. The speaker smiled. Then he put up the note on the blackboard and asked the
same question. Again, we put up our hands. The speaker kept 8,
but said 9 .
Suddenly, he threw the note onto the floor! Then he asked the same question for 10time.
I didn't understand the speaker. Why was he asking the same question again
and again? I didn't know 11 to
do. I wanted the note, so I put my hand up again. "You have all just told me
how to become successful." He said to us 12 the note in his hand. "The note is worth twenty
yuan. It is always worth twenty yuan, even though I throw it on the floor. You are
like the note. No matter what happens to you, you still have your worth."
Hearing those words, I 13 deeply.
Suddenly, I realized I was worth a lot. I may have failed, but it doesn't mean I
14 do well in the future. If I believe
in15I will be successful!
