CHANCE

The 1997 financial crisis left Thailand and our family in shambles. When I was in Grade 6, I asked my mother for a piano. "Everyone's on page eight already and I still can't play C,D,E", I would moan. In our school's music class, we were learning basic piano, and I was lagging behind. The idea of coordinating ten fingers onto the keys together accurately and rhythmically was baffling to me and I was convinced I could never play a piece of music in my life. Now, a price for a piano was not cheap, and with the financial problems we and our country were experiencing, a piano was not an option. Of course, I would not have known all that as an eleven-year-old boy who at the time only wanted to pass his music class. The next day, my mom bought a toy piano for about 100 Baht. It had 10 baby-sized keys, with big cartoon faces plastered on the top. To a boy who is oblivious to the gravity of our financial situation, it looked ridiculous. "I can't play on that! It's a baby's toy, my hands don't even fit", I showed it to her, laughing - looking at hindsight - rather ungratefully. My mom didn't seem to mind though as she said "Alright son, I will get you a proper keyboard." After a discussion with my dad, they decided to get me a keyboard, 9000 Baht, right from the emergency savings. It wasn't a bad keyboard either, certainly didn't merit my limited talent in piano. Nevertheless, my parents bought it with some of the last savings they had, and needless to say, I loved it. I would play on it every day and night, sometimes so late I got told to stop by my family trying to sleep. In one month I could play every song in the school's music book and not long afterwards, took up 3 more instruments: violin and guitar and tuba. I am now the leader of the school orchestra and string orchestra and played in the concert band and jazz band. In short, I now breathe music. Back then, I was a boy with seemingly no talent or goal in life, until I received from my parents the greatest gift I never requested, and no it's not the toy piano or the keyboard, the gift of chance; the chance for me to have a talent, an aspiration, an identity, and I took it, without knowing, with my 10 now dexterous fingers.

Although I still love playing music, I now have a new goal in life, which came from my sudden revelation after seeing more and more of the graphically violent world we live in: that whilst playing music can reconnect a broken soul; it cannot heal a dying heart. Today, I know that I wanted to become a doctor and save people's lives, and that it is all I would ever want to do, even if it means going through hell of a refugee camp, or a slum village ravaged with disease. I have ambitions so great that they are ready to burst into action. Now I just need a chance, a medium for me to express my dreams, and it must not be just some toy piano or even a fully functional keyboard, but the grandest of the grand pianos that with the help of the instrument, I can make music that can change the world.
