this evening i went to the ktv with some of my good friends.

　　this was the first time that i had been to a ktv. at first i didn't want to go. i had been in a bad mood the whole afternoon because i didn't do well in the math exam. at the ktv, everybody sang his favourite songs very happily except me. i was the only one of the audience.

　　i didn't dare to have a try. because i was afraid that i couldn't sing well. encouraged by my classmates, i picked up the microphone and sang an english song "i believe i can fly"

　　i have become cheerful now and above all i've regained selfconfidence. i believe that the worst enemy in one's life is oneself. i shouldn't lose heart just because of one or two failures. because i still have chances to try.
