Whatever misfortune you face, just hold up your head and face it with a smile! I got to know this from a musical soul.
The other day I was feeling quite      , having just been laid off from my job. With so many       to pay, I was wondering what was going to happen to my family.
I got off the bus when I heard piano music and singing rising above the noise of the      . I walked a bit slower, trying to find out where it was coming from. Through the       I saw a young lady sitting at a piano with a box next to her.
She was singing songs about love and her sweet voice       me a bit. Then I stood there watching her playing, thinking that it must take       to perform on her own in front of hundreds of people she didn’t know. 
She might have felt my       for she occasionally looked in my direction.
By now I was telling myself that I could at least tell her how good she sounded. I walked       and put some money in her box and she expressed her thanks with a smile on her face.
I asked her      , “Why are you playing the piano in the middle of this crowded place?”
She explained to me that she sees so many       people in the world that she is trying to relieve the pain by       motivational(激励的)music.
Instead of continuing my way home, I said to her, “I have been going through a        time lately, but you’ve made me       again.”
“I’m happy that I could be       to you,” she replied. “Why are you so sad?”
I told her my story and said, “I’m not so       about what to do….”
“You see, here’s the      ,” she responded. “When you were walking, your head was down.” She looked me in the eyes and went on, “Don’t look defeated, because       comes in different ways and if your head is down you might never see it. You should       more … lift your head up.”
I was really       by what she said! I did hold my head up and soon got through the difficult time.
So       in trouble, just face it bravely and you are sure to overcome your difficulty sooner or later.
