     I was feeling a little blue because my mother had been laid off from her job and she had lots of bills to

pay. It left me wondering what was going to happen to us now. But it reassured me some when my mother told me she was relieved to be leaving since her boss wasn't the nicest person to be around.

     I got off the college shuttle bus and started walking. That's when I heard piano music and singing

rising above the noise of the people and the traffic. I walked a little slower so I could find out to where it

was coming from. Through the crowd I saw a young lady sitting at a piano with a carriage next to her.

     She was singing songs about love, keeping on trying, and not underestimating the power within

yourself. The way she was singing comforted me a bit. I stood there watching her play for about fifteen

minutes, thinking that it must take courage to perform on your own in the middle of a crowded New York

ferry terminal.

     So I stood there listening.

     She must have felt my presence because she would occasionally look in my direction. By now I was

telling myself that if she could perform in front of hundreds of people she didn't know then I could at least

tell her how good she sounded. I walked over and put some money in her carriage and she said, "Thank

you." Instead of continuing my way home, I said to her, "I have been going through a rough time lately,

but you've made me hopeful again."

     "I'm happy that I could help," she replied. "Why are you so sad?"

     "Well, my mum told me she had got fired from her job, and that made me sad. I'm not so sure what

to do ..."

     "You see, here's the problem," she explained. "The way you were walking, your head was down.

Don't look defeated, because opportunity comes in different ways and if your head is down you might

never see it. You should smile more ... lift your head up."

     I smiled faintly, amazed by how she was encouraging me. So, I asked her, "Why are you playing the

piano in the middle of a crowded place? I've seen you do this more then once."

      She explained to me that she sees a lot of negative people in the world and she tries to alleviate the

pain and bring more positivity by sharing motivational music. She told me that when she wasn't making

music she studied psychology. So, that was how she knew some of the things she was telling me.

     I smiled a little wider because I knew that she was doing a good thing. So, after that we parted, my

heart touched and lightened by a musical soul!
